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>

Answer:

5x+8y

Step-by-step explanation:

We can first open the brackets by using the distrubitive propety.

2(x+4y)+3x

2x+8y+3x

Now we can combine like terms.

5x+8y.

I combined the 3x and the 2x. This works because imagined I have 3 of something then I got 2 more of that something I would now have 5 of that something.
