Question

The distance around the edge of a circular pond is 88m. the radius in meters is ?

(a)88π
(b)176π
(c)88/π
(d)88/2π​

Answer 1

Answer: (d) 88/ 2π

Explanation:

Perimeter = 88m

Perimeter of a circle = 2πr

88 = 2π x r

r = 88 / 2π

Answer 2

88/2π​ = r

Explanation:

The circumference is 88 m

The circumference is given by

C = 2*pi*r

88 = 2 * pi *r

Divide each side by 2 pi

88 / 2pi = 2 * pi *r / 2 * pi

88 / 2 pi = r
