Question

Find out the area and perimeter of circle of radius 7cm

Answer 1

Explanation:

area of circle=πr^2

=3.14*(7)^2

=3.14*49

=153.86 cm^2

perimeter of a circle(circumference)=2πr

=2*3.14*7

=14*3.14

=43.96 cm

Answer 2

`area = (\pi)/(4) * {r}^(2) \\ = (\pi)/(4) * {7}^(2) \\ = (\pi)/(4) * 49 \\ = 38.48451000647 \: cm \: ans......`
