Question

the circumference of a circular garden is 66m find its diameter ( take r=22by7

Answer 1

2
$2(pi)r = 66$
therefore r=66/2pi

66*7/2*22

=21/4
=3.5

Answer 2

Here is your solution

Given :-

circumference of a circular garden is 66m

find its diameter =?

we know that

Circumference = 2×π × r

66=2×(22/7)×r

66=44r/7

(66×7)/44=r

21/2=r

Diameter = 2r

=2×(21/2)

Diameter =21m

Hope it helps you
