Question

Emily is making a meal for her family. She uses coconut milk for the dessert she is making.

The coconut milk is in a can but she 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

576 cm³

Explanation:

The formula for the volume of a cylinder is

V = πr²h.

We have a diameter of 8; this makes the radius half of that, or 4.

Using 3 for π, 4 for the radius and 12 for the height, we have

V = 3(4²)(12) = 3(16)(12) = 48(12) = 576

Answer 2

We have been given that

diameter = 8 cm

So, radius = 4 cm

height = 12 cm

Volume =
`\pi r^(2) h`

`= 3(4^(2) )(12)`

= 48 × 12

= 576 cubic cm.

Hence, the volume of the coconut milk in the can is 576 cubic cm.
