A sector of a circle whose radius is 4 centimeters, has a central angle of 30 Which of the following. which of following represents the area of this sector in square centimeters?
(1). 12π/5
(2). 8π/15
(3). 4π/3
(4). 6π/5
Answers
Answer:
area of the sector =4π/3 cm²
Step-by-step explanation:
To find the area of the sector, we will follow the steps below;
first write the formula for finding area of a sector
area of a sector = Ф/360 × πr²
where r is the radius
from the question given
Ф= 30 and radius = 4 centimeters
we can proceed to insert the values into he formula above
area of a sector = Ф/360 × πr²
=30/360 ×π×4²
=1/12 ×π×16
=16π /12
=8π/6
=4π/3
area of the sector =4π/3 cm²

Nantai is hiking in Death Valley. He starts out at Badwater Basin, the lowest point of DeathValley at an elevation of 282 feet below sea level. He walks northward towards Telescope Peakin the Panamints and reaches an elevation of 2400 feet. How much did his altitude change?
Answers
Answer:
2682
Step-by-step explanation:
he walked 282 feet from below sea level and is now at ground level, so he increase by 282 then he continues 2400 feet, so he walked 282 in below sea level plus the 2400 feet above ground level, so 282 plus 2400 equals 2682
Use the equation below to find v, if u=17, a=4, and t=8. 4=u+at
Answers
Answer:
This is not a valid equation, as the left-hand side is not equal to the right-hand side.
Therefore, there may be an error in the given equation or values. Please check and provide the correct equation or values, so that we can help you find the value of v.
Step-by-step explanation:
The given equation is:
4 = u + at
where u = 17, a = 4, and t = 8.
Substituting the given values, we get:
4 = 17 + 4(8)
Simplifying the right-hand side:
4 = 17 + 32
Combining like terms:
4 = 49
This is not a valid equation, as the left-hand side is not equal to the right-hand side.
Therefore, there may be an error in the given equation or values. Please check and provide the correct equation or values, so that we can help you find the value of v.

A project will take a total of 720 person-days to complete. If the project must be completed in 30 days, how many people must be employed? PLEASE HURRY
Answers
Answer:
192 hours per day / 8 hours per person per day = 24 people
Step-by-step explanation:
Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:
720 person-days x 8 hours = 5,760 hours
To complete the project in 30 days, the total number of hours needed per day is:
5,760 hours / 30 days = 192 hours per day

Step-by-step explanation:
First, add 11 to both sides of the inequality
-1+11 ≥ -11+11 + x
Second, simplify
10 ≥ x
Third, flip the sign
x ≤ 10
Lastly, graph the solution on the number line
The line under the sign indicates that the point you will plot on the 10 will be a closed circle. The sign is facing the right, so the arrow will extend to the left.
Answer: The Solution is x≤10 and inequality notation is (-∞,10] and the point on the graph should be on 10

Refer to the circle to the right.
a. Find the circumference of the circle. use 3 as the estimate of π.
b. Find the circumference of the circle using 3.14 for π.
c. Another estimate of π is 3.14159. Find the circumference using this estimate.
d. What do you notice about the estimate used for π and the circumference of the circle?
Answer and explain how you got to your answer to get brainliest
Answers
Answer:
a. If π = 3 => C = 10 x 3 = 30
b. if π = 3.14 => C = 10 x 3.14 = 31.4
c. if π = 3.14159 => C = 10 x 3.14159 = 31.4159
d. using the whole number of π makes the calculation easier but using the π with more decimals will make the result more accurate.
Step-by-step explanation:
Diameter = 10 => radius = 10/2 = 5
Circumference: C = 2πr = 2π(5) = 10π
a. If π = 3 => C = 10 x 3 = 30
b. if π = 3.14 => C = 10 x 3.14 = 31.4
c. if π = 3.14159 => C = 10 x 3.14159 = 31.4159
d. using the whole number of π makes the calculation easier but using the π with more decimals will make the result more accurate.
Answer: hope this helps ♡
a. C = 3 × 10 = 30cm
b. C = 3.14 × 10 = 31.42cm
c. C = 3.14 × 10 = 31.42cm
d. The bigger the estimated value of π, the bigger the circumference. The circumference gets more accurate when you use the whole number of π.
Step-by-step explanation:
C = π ×d (or 2r) d =10
a. π = 3 C = 3 × 10 = 30cm
b. π = 3.14 C = 3.14 × 10 = 31.42cm
c. π = 3.14159 C = 3.14 × 10 = 31.42cm
d. The bigger the estimated value of π, the bigger the circumference. The circumference gets more accurate when you use the whole number of π.

Answers
Answer:
I. Length: 43 inches
II. Width: 15 inches
III. Height: 5.5 inches
Step-by-step explanation:
To determine the dimensions of the new box, we need to calculate the space required for a dozen donuts lying flat, including the additional space of one inch.
Since the diameter of each donut is 3.5 inches, the width of the box must be greater than or equal to 3.5 x 4 = 14 inches to accommodate four donuts placed side by side.
Similarly, since the height of each donut is 1.5 inches, the height of the box must be greater than or equal to 1.5 x 3 = 4.5 inches to accommodate three donuts stacked on top of each other.
Finally, since the length of each donut is 3.5 inches, the length of the box must be greater than or equal to 3.5 x 12 = 42 inches to accommodate a dozen donuts lying flat.
Adding one inch to each dimension gives us a final box size of:
Length = 42 + 1 = 43 inches
Width = 14 + 1 = 15 inches
Height = 4.5 + 1 = 5.5 inches
Therefore, the dimensions of the new box should be:
I. Length: 43 inches
II. Width: 15 inches
III. Height: 5.5 inches
