Question

find the circumference of a circle whose radius is 10.5cm

Answer 1

circumference=2×22/7×10.5
=66 cm

Answer 2

Answer:

Circumference of given circle

(C) = 66 cm

Explanation:

Given radius of a circle (r) = 10.5 cm

$\boxed{ Circumference \: of \: a \: circle = 2πr }$

C = 2 × (22/7 ) × 10.5

= 2 × 22 × 1.5

= 66 cm

Therefore,

Circumference of given circle (C) = 66 cm
