If the circumference of a circle is 35 inches, which is closest to its area?
i don't know lolz
To find the area of a circle, you need to know the radius or the diameter. In this case, we only have the circumference, so we'll need to use a formula to find the radius first.
The formula to calculate the radius from the circumference is: radius = circumference / (2 * π), where π (pi) is a mathematical constant approximately equal to 3.14159.
Now, let's calculate the radius:
radius = 35 inches / (2 * 3.14159)
radius ≈ 5.5658 inches
Once we have the radius, we can use another formula to find the area of the circle:
area = π * radius^2
Now, let's calculate the area:
area = 3.14159 * (5.5658 inches)^2
area ≈ 97.5205 square inches
So, the closest area to the circle with a circumference of 35 inches is approximately 97.5205 square inches.
What are your answer choices What is your answer?
C = pi * 2r = 35 in.
3.14 * 2r = 35,
r = 5.6 in. = radius.
A = pi * r^2.
