Question

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

Answer 1

Sphete B have a surface area of 48 square feet

Explanation:

Two spheres of

Sphere A the smallest and sphere B the biggest has a scale factor of 1/3

Sphere A has surface area of 16 square feet.

Let's determine the surface area of sphere B.

Sphere A /sphere B = 1/3

Sphere A = 16

16/sphere B = 1/3

3*16= sphere B *1

48 = sphere B

Sphete B have a surface area of 48 square feet
