Question

What is the approximate circumference of a circle that has a radius of 90? Use 3.14 for
and express your answer to the tenths place. (1 point)

Answer 1

since its radius, you have to square it so 90 * 90 then 8100 * 3.14

Answer 2

Circumference = 2 * π * radius
Circumference = 2 * 3.14 * 90
Circumference = 565.2

Therefore, the approximate circumference of a circle with a radius of 90 is 565.2.
