Question

What is the exact volume of the sphere?

Answer 1

Here's the problem

Answer 2

The 6.5 represents the radius

Answer 3

1150.35 3/4*pi*r*3

Answer 4

The formula for the volume of a sphere is
\[V = \frac{ 4 }{ 3 }\pi*r ^{3}\]

Answer 5

Here are the choices

Answer 6

\[V = \frac{ 4 }{ 3 }(6.5)^3(\pi)\]

Answer 7

V = 1150.35 ft^3

Answer 8

thats what i said but it doesnt match up with the answers tho ???

Answer 9

Okay for the choices they have their answers in pi

Answer 10

Don't evaluate the pi as 3.14 in this case. Keep it as is. So let's try it again.

Answer 11

\[V=\frac{ 4 }{ 3 }(6.5)^3(π)\]

Answer 12

\[V = \frac{ 4 }{ 3 }(274.625)\pi\]

Answer 13

Thank you guys for your help

Answer 14

\[V = 366.1666667\pi \]

Answer 15

SO your answer would have to be C

Answer 16

So it's 366.16

Answer 17

correct :)

Answer 18
