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?

    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

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

    \[(4/3) \Pi 9= 36/3 \Pi= 12\Pi\]

    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 \[6\Pi\]
