Answer 2

Answer :

• Area of circle = 616cm²

Given :

• Circumference = 88cm

To find :

• Area of circle

Solution :

Given ,

• Circumference = 88cm

As we know that,

• Circumference = 2πr

First we need to find the radius

》 Circumference = 2πr

》2 × 22/7 × r = 88

》r = 88 × 7 / 2 × 22

》r = 616/44

》r = 14cm

Hence, Radius is 14cm

Now we have to find the area of circle

As we know that,

• Area of circle = πr²

where r is radius

》Area of circle = πr²

》Area of circle = 22/7 × (14)²

》Area of circle = 22/7 × 14 × 14

》Area of circle = 22 × 2 × 14

》Area of circle = 616cm²

Hence , Area of circle is 616cm²
