Question

5. Tick the correct answer in the following and justify your choice. If the perimeter and
the area of a circle are numerically equal, then the radius of the circle is
(A) 2 units
(B) pie units
(C) 4 units
(D) 7 units​

Answer 1

$\mathtt{\huge{ \fbox{Solution :)}}}$

If the perimeter and the area of a circle are numerically equal , then the radius of the circle is 2 units

$\mathtt{\huge{ \fbox{Explaination :)}}}$

Let us assume that , the radius of circle be " r " and the perimeter and area of circle are equal

$\sf \mapsto 2 \pi r = \pi {(r)}^{2} \\ \\\sf \mapsto 2 = \frac{\pi {(r)}^{2} }{\pi r} \\ \\\sf \mapsto r = 2 \: units$

Hence , if the radius of circle is 2 units then the perimeter and area of circle are will be equal
