Question

The sum of the circumference and diameter of a circle is 116 cm. Find its radius

Answer 1

r = 18.47

Explanation:

Circumference - 2πr

Diameter - 2r

Given: 2πr + 2r = 116

2r(π+1) = 116

Value of π = 3.14

2r(3.14) = 116

r = 18.47

Answer 2

Explanation:

A.t.q,

2πr+2r=116 cm

2r(π+1)=116 cm

2r(22/7+1)=116 cm

2r(22+7/7)=116 cm

2r=116×7/29

2r=28 cm

r=28/2

r=14 cm
