Question

find the circumference and the area of a circle of diameter: {42} {110} and 132m​

Answer 1

Circumference of circle For diameter 42

Radius = diameter/2

= 42/2

=21m

Circumference of Circle = 2πr

= 2 * 22/7 * 21

=2* 22* 3

= 44*3

= 132m

Area of circle = πr^2

=22/7 * 21* 21

=22* 3* 21

=66* 21

= 1386m
