Question

The Candle Factory is producing a new candle. It has a radius of 3 inches and a height of 5 inches. What is the surface area of the candle? Use 3.14 for Pi. Round to the nearest whole cubic inch. A cylinder with a radius of 3 inches and height of 5 inches. Recall the formula S A = 2 pi r squared + 2 pi r h. 48 square inches 151 square inches 251 square inches 414 square inches

Answer 1

We are looking for the amount of wax it will take to fill up that size candle mold to make that candle. That means that we are looking for the volume of wax, and the shape is a cylinder. The volume formula for a cylinder is

For us, that will look like this:

which translates to

V = 3.14(9)(5) which gives us a volume of 141.3 cubic inches. Rounding to the nearest cubic inch is simply 141 cubic inches of wax.
