Question

Find the area of a circle of radius 7cm

Answer 1

here is ur answer........

Answer 2

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 ${cm}^{2}$
