Question

what is the ratio of the area of the circle to the area of the semi circle ? and How?​

Answer 1

Answer:

Step-by-step explanatStep-by-step explanation:

Consider radius 'r' is same for both circle and semicircle then

The area of circle =

The area of semicircle=

Now, the ratio of area of circle and semicircle with same radius will be

Thus, the ratio of area of a circle to the area of semicircle is 2:1.ion:

Answer 2

Answer:

2 : 1

Step-by-step explanation:

area of a circle = 2πr

area of a semi circle = 1/2 *2πr = πr

ratio of area of circle to that of semicircle = 2πr/πr = 2/1 = 2 : 1
