Question

find area of circle whose cicumference is 112m​

Answer 1

Answer:

Given:

Circumference of circle=112m

2×pi×r=112m

2×22/7×r=112m

44/7×r=112m

r=112×7/44

r=3×7

r=21

area of circle=pi×r×r

=22/7×21×21

=22×3×21

=66×21

=1386sqm

Answer 2

Explanation:

here p is pie which has value 22/7

2*p*r =112

p*r=112/2

p*r=56

r=56×7/22

Area =p×(r^2)

=p×r×r

=56×56×7/22

=28×56×7/11

=998.7m
