sleepyjess · Answer

the formula for volume of a sphere is $\dfrac{4}{3}\pi r^3$

sleepyjess · Answer

you know the diameter is 15 so what is the radius (r)?

anonymous · Answer

Its radius would be 7.5 @sleepyjess

sleepyjess · Answer

correct so substitute that in for r
now we have $\dfrac{4}{3}\pi ~7.5^3$

sleepyjess · Answer

$7.5^3=421.875$
$421.875*3.14 \leftarrow this~is~\pi$

sleepyjess · Answer

are you following me so far?

anonymous · Answer

yes i am .

anonymous · Answer

@sleepyjess so i would multiply 421.875 & 3.14 correct ?

sleepyjess · Answer

yes

sleepyjess · Answer

that is 1324.6875
the multiply that by 4/3 and you have your final answer

anonymous · Answer
