Question

1. Find the circumference of the circles with the following radius. (Take TI =n =22/7 A = 14mm B =21cm C =28

​

Answer 1

Answer:

(a) Radius(r) = 14cm

Circumference= 2πr =2 x 22/7 x 14

(b) Radius(r)=21cm

Circumference= 2πr =2 x 22/7 x 21

=132cm

(c) Radius(r) = 28mm

Circumference= 2πr =2 x 22/7 x 28

=176mm

Answer 2

circumference of the circles(A) = 2pi×R

=2×22/7×14cm

=88cm

circumference of the circles(B) = 2pi×R

=2×22/7×21cm

=132cm

circumference of the circles(C) = 2pi×R

=2×22/7×28cm

=176cm
