Solving for the circumference and using the formula for the circumference we got the radius as 74.95 feet

Mensuration of Flat Shapes

Given Data

1/4 of the circumference = 117.75 feet.

Let the circumference be x feet

1/4*x = 117.75

x/4 = 117.75

cross multiplying

x = 4*117.75

x = 471 feets

The expression for the circumference is given as

C = 2πr

471 = 2πr

Making r subject of formula we have

r =  = 471/2*3.142

r = 471/6.284

r = 74.95 feet
