Question

I need to show work also​

Answer 1

376.8 cubic centimeter of wax are needed for the candle.

Solution:

Radius of the cylinder = 2 cm

Height of the cylinder = 30 cm

The value of π = 3.14

To find how much wax are needed to make the candle:

Volume of the cylinder = $\pi r^2 h$

                                      = 3.14 × 2² × 30

Volume of the cylinder = 376.8 cubic centimeter

Hence 376.8 cubic centimeter of wax are needed for the candle.
