What is the volume of a hemisphere with a radius of 6.5 ft, rounded to the nearest tenth of a cubic foot?

574.9ft^3.

Step-by-step explanation:

radius (r) = 6.5feet

π=3.14

volume of hemisphere=2/3 x π x r^3

Volume=2/3 x 3.14 x (6.5) ^3

Volume=2/3 x 3.14 x 6.5 x 6.5 x 6.5

Volume = (2x3.14x6.5x6.5x6.5) ➗ 3

Volume=1724.645 ➗ 3

Volume=574.9ft^3

575.2 ft^3

Step-by-step explanation:

The volume of a sphere of radius 6.5 ft is V = (4/3)(pi)(6.5 ft)^3.

The volume of half that sphere, the hemisphere in question, is half of this expression:  (1/2)(4/3)(pi)(6.5^3) ft^3:

575.2 ft^3

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
