The radius IS given, since height of hemisphere = radius of hemisphere!
pi*9*height = 72 Divide both sides by pi*9 to find the height: height = 2.546479089 cm
pi*radius2*height = volume Make the height the subject of the above formula:- height = volume/pi*radius2
The volume of a cylinder is found by multiplying the area of its base times its height.
To calculate the volume of a cylinder, you use the formula V = πr²h, where V is the volume, r is the radius, and h is the height. Plugging in the values given, V = π(7²)(10) = 490π cubic inches. Therefore, the volume of the cylinder is 490π cubic inches.
