Question

If radius of a circle is 28cm then find Area of a circle.
​

Answer 1

Step-by-step explanation:

2464cm² is correct answer

Answer 2

Answer:

Area of circle is 2464 ${cm}^{2}$

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 = $2464$

Hence,

Area of circle is 2464 ${cm}^{2}$
