Will mark a sphere has a diameter of 9 inches. what is the volume of the sphere rounded to the nearest tenth? use 3.14 for pi.

The volume of sphere is 381.51 cubic inches.

Step-by-step explanation:

We are given the following information in the question:

Diameter of sphere = 9 inches

Radius of sphere =

Volume of sphere =

Putting the vales, we get,

The volume of sphere is 381.51 cubic inches.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
