Question

Find the area of the circle if r = 5 meters. Leave the answer in terms of π. A) A =100π square meters B) A =25π square meters C) A = 5π square meters D) A = 10π square meters

Answer 1

The answer is B) A = 25π  because we were given the radius 5 and 5^2 is 25. 

Answer 2

The area of circle is $25\pi \text{ }{{\text{m}}^{2}}$.

What is area of circle?

The two dimensional area enclosed by a circle, the formula for area of circle is,

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

Where $A$ is the area of circle, $r$ is the radius.

It is given that, the $r$ is $5m$.

We have to find the area of circle.

So,

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

$A=\pi \cdot {{\left( 5 \right)}^{2}}$

$\therefore A=25\pi$

Hence, the area of circle is $25\pi \text{ }{{\text{m}}^{2}}$.
