Question

if the radius is 279 in. and the circumference is 558 in. what is the area?

Answer 1

The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle.

Given that the circumference is 558 in., we can set up the equation:

558 = 2π(279)
558 = 558π
π = 1

Now, with the value of π, we can calculate the area of the circle using the formula A = πr^2:

A = π(279)^2
A = π(77941)
A = 77941π
A = 77941(1)
A = 77941 in^2

Therefore, the area of the circle with a radius of 279 in. is 77,941 square inches.
