Question

A Chick-o-stick is the inside of a Butterfingermade into a cylinder. A Chick-o-stick has adiameter of 1.8 cm and a height of 9.6 cm, ifwe were to cover it in chocolate, how mucharea needs to be covered?

Answer 1

It is given that the diameter is 1.8 cm so the radius is 0.9 cm

It is also given that the height is 9.6 cm.

It needs to be covered in chocolate so the surface area of the cylinder needs to be calculated.

The surface area of the cylinder is given by:

`A=2\pi* r(r+h)`

Substitute the values to get:

`\begin{gathered} A=2*\pi*0.9(0.9+9.6) \\ A=59.3761cm^2 \end{gathered}`

Hence the area of chocolate required is 59.3761 square centimeters.
