Answer:

180 units^2

Step-by-step explanation:

The formula to find the area of a sphere is:

A=4(pi)(r)^2

A sphere with radius 2r has an area = 4π(2r)² = 4π.4r² = 16πr²

The ratio of the larger sphere to the smaller = 16πr² : 4πr² = 4 : 1

If the area of the smaller sphere is 45 units then the area of the larger sphere is 45 x 4 = 180 units^2.

hope this helps :)
