Question

the circumferance of a circle is 123.2cm find its area nd radius

Answer 1

Circumference of circle = 2 * pi * r
Given circumference = 123.2 cm
Hence
2 * pi * r = 123.2
r = 61.6 * 7 /22
r = 19.6 cm
Area of circle = pi * r * r
Area = 22/7 * 196/10 * 196/10
Area = 22/7 * 98/5 * 98/5
Area = 1207.36 cm^2
