Question

A piece of wire in the form of a rectangle with the dimensions 12 m by 10 m is bent to form a circle . Find the diameter of the circle

Answer 1

14.01m

Explanation:

Perimeter of the rectangular wire = circumference of the circle

Perimeter of the rectangular wire = 2(L+W)

Perimeter if the rectangular wire = 2(12+10)

Perimeter if the rectangular wire = 2(22)

Perimeter if the rectangular wire = 44m²

Circumference of the circle = πd

44 = πd

d = 44/3.14

d = 14.01m

Hence the circumference of the circle is 14.01m
