What is the volume of a hemisphere with a radius of 6.5 feet rounded to the nearest 10th of a cubic foot

=574.9 ft^3

Step-by-step explanation:

The volume of a sphere is V = 4/3 pi r^3

Take half of that to get a hemisphere

1/2 *V = 1/2 *4/3 pi r^3

         =2/3 pi r^3

So the volume of a hemisphere is

V = 2/3 pi r^3

   = 2/3 pi (6.5) ^3

    = 2/3 ( 3.14) * (6.5)^3

    =574.8816667

Rounded to the nearest tenth

   =574.9 ft^3

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

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
