Seven less than a number is twenty (as an equation)

1 answer:

4 0

You're expression is correct if it's asking for a number that is less than 7. But if the problem is asking for some number less than seven as in seven less some number, then it's 7-n. For example: 4 less than 7 is 7-4.

Hope this helps!

Answer:

Exact volume = 294π in³

Approximate volume = 923.6 in³

Explanation:

The volume of a cylinder can be calculated using the following rule:

volume = πr²h

where r is the radius and h is the height of the cylinder

In the given cylinder:

radius = r = 7 in

height = h = 6 in

Substitute with the givens in the formula to get the volume:

Volume of cylinder = πr²h = π(7)²(6) = 294π in³ ≈ 923.6 in³ to the nearest tenth

Hope this helps :)
