pi * radius^2 * height / 3

3.14 * 6^2 * 7 / 3

3.14 * 36 * 7 /3

3.14 * 252 /3

A cylinder has a height of 6 inches and a radius of 2 inches. What is its volume? Use a 3.14 and round your answer to the neares

Olenka [21]

Answer:

$\boxed {\boxed {\sf 75.36 \ inches^3}}$

Step-by-step explanation:

The volume of a cylinder is found using this formula:

$v= \pi r^2h$

Th height is 6 inches, the radius is 2 inches, and we are using 3.14 for pi. Substitute the values into the formula.

$v= (3.14)(2 \ in)^2(6 \ in)$

Solve the exponent.

(2 in)²= 2 in * 2 in = 4 in²

$v= (3.14)( 4 \ in^2)(6 \ in)$

Multiply the first two number.

$v= 12.56 \ in^2 (6 \ in)$

$v= 75.36 \ in^3$

This is already to the hundredth place, so we do not need to round.

The volume of the cylinder is <u>75.36 cubic inches.</u>

Complete the statements about these similar pyramids.

A ratio shows us the number of times a number contains another number. The ratio of the sides, base area, and volume are equal to 3:1, 9:1, and 27:1, respectively.

<h3>What is a Ratio?</h3>

A ratio shows us the number of times a number contains another number.

Given the two lateral sides of the pyramids, therefore, the ratio of the sides of the pyramid can be written as,

Length of pyramid A: Length of pyramid B = 15:5 = 3:1

Let the length of the base of the pyramid is represented by a.

The ratio of the base area can be written as,

Area of Base of A: Area of base of B = (3a)²:a² = 9:1

The ratio of the volume can be written as,

Volume of A: Volume of B = (3l×3b×3h)/3 : (lbh)/3 = 27:1

Hence, the ratio of the sides, base area, and volume are equal to 3:1, 9:1, and 27:1, respectively.
