Approximate the change in the volume of a sphere when its radius changes from r= 5ft to r= 5.1ft (v(r)= 3/4 pi r^3)?

18.03 cubic feet

Step-by-step explanation:

Hello,

Step 1

find the volume of the sphere when radius= 5 ft

Step 2

find the volume of the sphere when radius= 5.1 ft

Step 3

Compare the Volumes to find the change

the volumen of the sphere with radius = 5.1 is 1.06 times bigger than the first one(r=5)

Now, find the change

change=18.03 cubic feet

Have a great day.

the correct answer is 5 6 and 7
