Answer 2

Given -

Radius of circle is 70

To find -

The area of circle

Solution -

As we know that,

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

Where, r is a radius of circle.

Put the value of r we get

Area of circle = $\pi \times {70}^{2}$

Square means multiply the given values with itself twice.

$70 \times 70 = 4900$

So, Square of 70 is 4900

Area of circle = $\pi \times 4900$

The value of π is 3.14.

Area of circle = $3.14 \times 4900$

Area of circle = $15386$

Hence,

Area of circle is 15386${unit}^{2}$.
