Answer:

Area of circle is 154  {cm}^{2}

Step-by-step explanation:

Given -

Radius of circle is 7 cm

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  {7}^{2}

Square means multiply the given values with itself twice.

 {7}^{2}  = 7 \times 7 = 49

Square of 7 is 49

Area of circle = \pi \times 49

The value of π is  \frac{22}{7}

Area of circle =  \frac{22}{7} \times 49

Area of circle =154

Hence,

Area of circle is 154  {cm}^{2}
