Question

the area of a circle is 616cm2 find its circumference​

Answer 1

Before finding the area, lets know how to find circumference using the area.

To find circumference:

2 x √πA

* pi can be estimated as 3.14

* A = area (616cm² here)

Using the formulas

A=πr2

C=2πr

Solving forC

C = 2 √πA = 2 x π x 616 = 87.9823

Or you can round it to 88 if you want.

Answer 2

Answer:

Circumference = 2πr=2×722×14=88 cm.
