Question

A circle has an area of 155 square feet what is the approximate radius of the circle

Answer 1

Explanation:

Area of square is π/r^2.

And π = 22/7.

So,

Area of square= π/r^2

155 ft^2 = π/r^2

155/22/7 ft^2 = r^2

155×7/22 ft^2 = r^2

49.3181 ft^2 = r^2

√49.318ft^2 = r

7.022 ft = r

Hence, radius of circle will be 7.022 feetfeet
