Question

A cylindrical candle has a diameter of 9 cm and height 12 cm.

It is placed in a cylindrical box.
There is a space of 0.5 cm between the candle and the box to allow for packing material.
a.) What is the height of the cylindrical box?
b.) What is the radius of the cylindrical box?
c.) What is the surface area of the box?

Answer 1

The radius of the cylindrical box is 4 cm.

Step-by-step explanation:

b) What is the radius of the cylindrical box?

To find the radius of the cylindrical box, we need to subtract the space between the candle and the box from the diameter of the candle. The diameter of the candle is 9 cm, so the radius is half of that, which is 4.5 cm. Subtracting the space, we have a radius of 4 cm for the cylindrical box.
