Question

A cylindrical candle that is 15 cm high has a diameter of 8 cm. Sketch

Answer 1

Answer:

• See the figure attached with the sketch of the shape.

• Volume = 0.75m³

Explanation:

The sketch of the shape is shown on the diagram attached indicating the height (15 cm), the diameter (8cm), and the radius (4cm).

The volume of a cylindrical shape is calculated with the formula:

      $Volume=\pi \times radius^2\times height$

The radius is half the diameter: 8cm / 2cm = 4 cm.

To express in terms of m (meters) convert the radius and the height from cm to m:

• 15cm × 1m/100cm = 0.15m

• 4cm × 1m/100cm = 0.04m

Substitute in the formula and compute:

        $Volume=\pi \times (0.04m)^2\times (0.15m)\\ \\ Volume=0.75m^3$
