Two spheres have a scale factor of 1:3. The smaller sphere has a surface area of 16 ft2. Find the surface area of the larger sphere.

48ft^2

Step-by-step explanation:

Given that:

Small and large Spheres have a scale factor of 1 : 3

Hence,

Smaller sphere = 1

Larger sphere = 3

Surface area of smaller sphere = 16ft^2

Hence,

Surface area of larger sphere = (3 * 16ft^2) = 48ft^2
