What is the volume of a hemisphere with a radius of 3 cm, rounded to the nearest tenth of a cubic centimeter?
Kaylis [27]

Formula: V = (2/3) π r 3.

Radius is 3cm.

So, now we can plug it in to solve for the volume.

V = (2/3) π 3^3

First, let's multiply 3^3.

3^3 = 27

Then, 27 x π = 84.82

After, multiply by 2/3.

84.82 x 2/3 = 56.55

Lastly, round 56.55 to the nearest tenth of a cubic centimeter.

56.55 = 56.6

Therefore the volume of a hemisphere with a radius of 3cm is 56.6cm^3.

A company makes wax candles in the shape of a cylinder. Each candle has a radius of 2 inches and a height of 7 inches. How much
podryga [215]

Answer:

18,471.6 cubic inches of wax will be needed

Step-by-step explanation:

We want the volume that will be required for 210 candles. We first find the volume of 1 candle by using volume of cylinder formula. Then multiply that answer by 210 to find volume of wax needed to make 210 such candles.

Volume of Cylinder is given by the formula:

V=\pi r^2 h

Where

r is the radius

h is the height

Given,

r = 2 in

h = 7 in

We substitute and find 1 candle volume:

Volume of 1 candle = \pi r^2 h = \pi (2)^2 (7) = 87.96

Hence,

Volume of 210 candles = 87.96 * 210 = 18,471.6 cubic inches
