Question

The radius of the circle is 28 cm then find the area of the circle

Answer 1

Answer:

r = 28cm

A = πr²

π = 22/7

A = 22/7 X 28 X 28

= 22 X 4 X 28

2464cm²

Answer 2

Answer:

Area of circle is 2461.76 ${cm}^{2}$

Step-by-step explanation:

Given -

Radius of circle is 28 cm

To find -

The area of circle

Solution -

As we know that,

Area of circle = $\pi {r}^{2}$

Put the value of r we get

Area of circle = $\pi \times {28}^{2}$

Square means multiply the given values with itself twice.

Square of 28 is 784

Area of circle = $\pi \times 784$

The value of π is 3.14.

Area of circle = $3.14 \times 784$

Area of circle = $2461.76$

Hence,

Area of circle is 2461.76 ${cm}^{2}$
