If the diameter of a student’s brain is about 6 inches,
and you assume its shape is approximately a
hemisphere, then what is the volume of the
student’s brain?

Question

anonymous · Answer

do you know the equation in finding the volume of a sphere. 
If I'm not mistaken I believe its (4/3) * pi * r^3 = Volume

anonymous · Answer

if you know the diameter the radius is half the diameter so r= 3 in

anonymous · Answer

i got 36pi

anonymous · Answer

Thats not it 
$$(4/3) \Pi 3^3$$

anonymous · Answer

$$(4/3) \Pi 9= 36/3 \Pi= 12\Pi$$

anonymous · Answer

thats the volume of the sphere but wait hold on. You want the volume of a hemisphere so its actually half a sphere. so the volume is 
$$6\Pi$$

previous qstn: i got 18 pi

anonymous · Answer

volume for hemisfrera is (2/3)pi r^3 and r=3

anonymous · Answer

Actually Pika is right I ^2  instead of ^3 sorry we all make mistakes.
