Question

The circumference of a circle is 26.4cm. Find its area

Answer 1

Circumference of circle=2πr
2πr=26.4
r=26.4×7/2×22
r=2.4×7/2×2
r=1.2×7/4
r=8.4/4
r=4.7
Area of circle =πr^2
=22×4.2×4.2/7
22×4.2×0.6
55.44cm^2
area =55.44cm^2
hope it helps u.....

Answer 2

circumference of circle =26.4cm
2×22/7×r=26.4
6.28×r=26.4
r=26.4/6.28
r=4.2cm
now,area of circle=22/7×4.2×4.4
=55.44cm^2
