Question

Adam uses coconut milk for the dessert.

The coconut milk is in a can but he doesn’t know how much the can holds.

The can is 12 cm high and the diameter is 8 cm.

Using the formula V = π r2 h, work out how much coconut milk is in the can.

Use 3 as a value for π.
Give your answer using the correct units.

Answer 1

The answer to your question is 575

Answer 2

Since we are already given the formula and all the information, the only thing that we have to do is input all the values and simplify until we get an answer. In addition, we must also note that the radius is 4 (because the diameter is equal to twice the radius, meaning that if the diameter is 8, the radius is 4). Using the formula and information given, we get:

Volume = 3 * (4)² * 12

Which simplifies to:

Volume = 3 * 16 * 12
Volume = 576

Now, we need to know the units. Since this is a 3d shape, and the unit for the lengths of the sides are centimeters, this answer will be in centimeters cubed. That means our answer is 576 centimeters cubed.
