Question

An architect is making a plan for a new circular playground. If the playground needs to be surrounded by a fence and the diameter of the playground is 25 meters, how much fencing needs to go up?

Answer 1

78.54 m

Explanation:

To obtain how much circular fence, we obtain the Circumference of the circular playground.

The Circumference of a circle, C = 2*pi*r

pi = 3.14 ; r = diameter / 2 = 25 /2 = 12.5 m

C = 2 * 3.14 * 12.5

C = 78.539816

Hence, the fencing which need to go up is ;

78.54 m
