Question

If radius of the big circle is double of a small circle, then the area of
the big circle is _________ of the small circle

Answer 1

Answer:

4times of the smaller circle

Answer 2

Answer:

4

Step-by-step explanation:

radius of the small circle=r; Area of the small circle= π(r)² = πr²

radius of the big circle= 2r; Area of the big circle= π(2r)² = 4πr²

Therefore, area of the big circle is 4πr²/πr² = 4 times of the small circle
