Question

How many cubic inches of a milkshake can you fit up to the brim of this cup without letting it overflow? The

cup is 10 inches tall, and the rim of the cup is 4 inches across. (Hint: the radius is half of the diameter.)

Answer 1

Assuming the cup is a right circular cylinder, it's volume is
`V=\pi r^2 h`

$h=10$, $r=\frac 42$

So the volume is $\pi\cdot(2)^2\cdot10=125.66$

hence you can fill up to 125.66 cubic Inches of milkshake
