Answer 2

Answer:

Area of circle is 12.57 ${unit}^{2}$

Step-by-step explanation:

Given -

Radius of circle is 2 unit

To find -

The Area of circle

Solution -

As we know that,

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

Where, r is radius of circle

Put the value of r we get

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

Square means multiply the given values with itself twice.

${2}^{2} = 2 \times 2 = 4$

Square of 2 is 4

Area of circle = $\pi \times 4$

The value of π is $\frac{22}{7}$

Area of circle = $\frac{22}{7} \times 4$

Area of circle = 12.57

Hence,

Area of circle is 12.57 ${unit}^{2}$
