Question

the diameter of circle is 12cm then the area of circle is
​

Answer 1

Step-by-step explanation:

D=12cm

Radius=12÷2=6cm

$area = \pi {r}^{2}$

$area \: of \: the \: circle \\ = \frac{ 22 }{7} \times {6}^{2}cm \\ = 113.1cm$

Answer 2

As per the Question,

Given data is Diameter 12 cm .

To find out the Area of circle.

As we know that,

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

Where,

r is a radius .

Radius is half of diameter.

So, r = $\frac{12}{2}$ = $6$

Put the value of r in the formula

Area of circle = $\pi 6^{2}$

Square means multiply the value with itself twice.

Square of 6 id 36 .

Area of circle = $\pi\times 36$

As value of π is 3.14

Area of circle = $3.14 \times 36$

Area of circle = $113.04$ $cm^{2}$

Hence,

Area of circle is 113.04 $cm^{2}$ .
