Answer 2

Given : Area of the circle = 38.5cm²

To find : Radius of the circle

Solution :-

Area of the circle = πr²

Let the Area be A and Radius be r

☛ $38.5\:=\: \dfrac{22}{7} \times r^2$

☛ $r^2\:=\:\dfrac{7}{22} \times 38.5$

Divide 38.5 by 22

☛ $r^2\:=\:7 \times 1.75$

☛ $r^2\:=\:12.25$

Taking square root on both the sides

∴ $r\:=\:3.5$

∴ The radius of the circle of $\boxed{\boxed{\tt{3.5\:cm}}}$
