Question

Find the area of circle of radius x cm and area of semicircle of same radius. What is the ratio of their areas?​

Answer 1

Step-by-step explanation:

2:5 is the correct ansAnswer

Answer 2

Answer:

Area of circle = $\pi$$x^{2}$

Area of semi circle = $\frac{1}{2} \pi x^{2}$

Ratio Of their area =$\frac{\pi x^{2}}{\frac{1}{2} \pi x^{2} }$

$\pi$$x^{2}$ will be cancelled on both sides so the ratio will be 1 : 1/2 Or 2:1
