Question

The area of a circle is 153.86 square meters. What is the diameter of the circle? Use 3.14 for π.

Answer 1

r = 7

Explanation:

You first need to know the formula for area of a circle. It is:

Area = π*r^2 (π = pi, r = radius)

Plug in for the given values:

153.86 = 3.14 * r^2

49 = r^2 (Divided both sides by 3.14)

r = 7
