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.

Answer 1

There is 576 cm³ of coconut milk in the can.

Step-by-step explanation:

The formula to calculate the volume of the can us given as:

`volume = \pi r^2h`

where:

π is a constant given = 3

r is the radius of the can =
`(diameter)/(2) = (8)/(2) = 4` cm

h is the height of the can = 12 cm

Substitute with these values in the given equation to get the volume as follows:

volume = 3 * (4)² * (12)

volume = 576 cm³

Now, assuming that the can is completely filled with coconut milk, the volume of milk will be equal to the volume of the can.

Hope this helps :)

Answer 2

Given:
Diameter = 8 cm
Height = 12 cm
Value of pi = 3

radius is 1/2 of the diameter. r = 8cm/2 = 4cm
Volume = π r² h
V = 3 * (4cm)² * 12 cm
V = 3 * 16cm² * 12 cm
V = 576cm³

Volume of the can is 576cm³. It is also the amount of milk inside the can.
