Question

The area of circle is 2464 square meters. what will its circumference be

Answer 1

Hey!!!

Area of circle = πr^2

2464 = 22/7 × r^2

√124 ×7 = r
√868 =r
r = 29.46 m

Circumference of circle = 2πr
= 2×22/7 × 29.46
= 185.177 sq. m

Answer 2

As the area of circle is 2464 square meters, 
 πr^2=2464
22/7×r^2=2464
r^2=2464×7/22
r^2=112×7
r^2=784
r=√784
r=28 meters-----1
circumference of a circle=2πr
                                       =2×22×28/7
                                       =44×4
                                       =176 meters
