Question

The area of a circle is 50.24m². Find its diameter and circumference. ​

Answer 1

Answer:

Given area of circle is 50.24m2.

We know that area of a circle is=πr2, where r is the radius of the circle.

So, πr2=50.24m2

r2=π50.24m2

r2=50.24×227 {since,π=722}

r2=15.985

r=3.998m

We know that circumference of a circle is =2πr

So, Circumfrence =2π×(3.998)m

Circumfernce =2×722×(3.998)m

Circumfrence=25.12m
