Question

Area of a circle with diameter $m$radius $n$ and circumference $p$ is

• A. $2\mathrm{\pi n}$
• B. ${\mathrm{\pi m}}^2$
• C. ${\mathrm{\pi p}}^2$
• D. ${\mathrm{\pi n}}^2$

Answer 1

The correct option is D

${\mathrm{\pi n}}^2$

Explanation for correct option:

We also know that,

Area of the circle$=\pi R^2$ where $R$ is the radius of the circle

Given radius$=n$

So, the area of the circle $=\pi n^2$

Hence, the correct option is (d)
