What is the volume of a right circular cylinder with a radius of 5cm and a height of 12cm?

Tom [10]

Answer: $V=942.47cm^{3}$

Step-by-step explanation:

1. To solve this problem you must use the following formula for calculate the volume of a right circular cylinder, which is shown below:

$V=\pi*r^{2}*h$

Where r is the radius and h is the height.

2. Now, you must substitute the values given in the problem. Therefore, you obtain the following result:

$V=\pi*(5cm)^{2}*(12cm)$

$V=942.47cm^{3}$

Air has a density of 0.001226 g/mL. What volume of air would have a mass of 1.0 lb? A. 2.7 mL B. 815.6 mL C. 37 mL D. 3.7 × 102

Andre45 [30]

Answer:

$Volume = 3.7\ * 10^2\ L$

Step-by-step explanation:

Given

$Density = 0.001226 g/mL$

$Mass = 1.0\ lb$

Required

Determine the volume of air

Density is calculated using:

$Density = \frac{Mass}{Volume}$

Substitute values for Density and Mass

$0.001226 g/mL = \frac{1.0\ lb}{Volume}$

Convert lb to grams

$0.001226 g/mL = \frac{1.0 * 453.592\ g}{Volume}$

$0.001226 g/mL = \frac{453.592\ g}{Volume}$

Solve for Volume

$Volume = \frac{453.592\ g}{0.001226 g/mL}$

$Volume = 369977.161501\ mL$

Convert mL to L

$Volume = 369977.161501\ L * 0.001$

$Volume = 369.977161501\ L$

Represent using scientific notation

$Volume = 3.69977161501\ * 10^2\ L$

Approximate

$Volume = 3.7\ * 10^2\ L$
