Question

Find the area of a circle whose radius is $6$ $cm$.

• A. $26$ $c{m}^2$
• B. $46$ $c{m}^2$
• C. $56$ $c{m}^2$
• D. $36$ $c{m}^2$
• E. none

Answer 1

The correct option is D $36$ $c{m}^2$

The radius of circle is $6$ $cm$

The area of circle is given as $\pi r^2$

$⟹\pi (6{)}^2$ $c{m}^2$

$⟹36\pi$ $c{m}^2$
