Question

TJ's Cat Food plans to use tins that are the shape of cylinders.

The internal measurements of a tin are shown.
8 cm
T
5 cm
I
b) Calculate the volume of cat food that the tin contains.
Round your answer to 1 decimal place

Answer 1

251.3 cm³

Explanation:

The diameter is 8 cm

So the radius is 8/2 = 4 cm

The height is 5 cm

Volume of tin can:

`\pi r^2 h`

r = 4 & h = 5

`V =\pi (4)^2 (5)\\V = \pi (16)(5)\\V = 251.3`

Answer 2

V = 251.3 cm³

Explanation:

Diameter 8 cm

Radius = 4 cm

Height = 5 cm

Volume of Cat Food contained by the tin can =
`\pi r^2 h`

Where r = 4 cm, h = 5 cm

V = (3.14)(4)²(5)

V = (3.14)(16)(5)

V = 251.3 cm³
