Question

Find the radius of a circle whose area equals the area of a rectangle that measures 2 ft. by 11 ft. (Use = 22/7)

a)7/2 ft.
b)√7 ft.
c)0.5√(14) ft.

Answer 1

Area of a rectangle would be A_rectangle = 2ft * 11ft
Since A_rectangle = A_circle and circle area formula is A_circle = pi * r^2
You can get r from there. Can you solve it yourself now?

Answer 2

yes i can thanks
