What is the scale factor of surface areas of the smaller sphere to the larger sphere? (2 points)
Radius of smaller sphere 250yd^3
Radius of larger sphere 686^3
Combine it with the following answers (Choose 2)
7
5
343
125
49
25
The scale factor of surface areas is equal to the square of the scale factor of the radii.
Scale factor of radii = 686/250 = 2.744
Therefore, the scale factor of surface areas = (2.744)^2 = 7.5165
The two closest answers are 7 and 5.
