Question

Find the area of a circle whose radius is 12.

Do Step by Step

Be 100% Sure​

Answer 1

Answer:

Area of circle= piersquare ( I hope you understand this formula)

Given radius=12

By substituting this with formula

we get

22/7×12×12=452.39

Answer 2

Given :-

• The area of a circle whose radius is 12 cm

To Find :-

• What is the area of the circle.

Formula Used :-

♣️ Area Of a Circle :

$\bigstar \: \color{magenta}{ \boxed{ \: \bf Area_{(Circle)} \: = \: \pi r ^{2} \: }} \: \color{black} \bigstar$

Where,

• $r \: = \: \bf radius$
• $\displaystyle\pi \: = \: \bf \frac{22}{7} \: or \: 3.14$

Solution :-

Given :

• Radius = 12 cm

According to the question by using formula we get,

$\implies \: \bf Area_{(Circle)} \: = \: \pi r ^{2}$

$\displaystyle \implies \: \sf Area_{(Circle)} \: = \: \ 3.14\times 12^{2}$

$\displaystyle \implies \: \sf Area_{(Circle)} \: = \: \ 3.14\times 12 \times 12$

$\displaystyle \implies \: \sf Area_{(Circle)} \: = \: \ 3.14 \times 144$

$\displaystyle \implies \: \bf \red{Area_{(Circle)} \: = \: \ 452.16}$

∴ The area of the Circle is 452.16 cm² .
