A cylinder has a volume of 245 cubic units and a height of 5 units. The diameter of the cylinder is
Vikki [24]

Answer:

The diameter is twice that, or approx. 7.90 units.

Step-by-step explanation:

the equation for the volume of a cylinder of radius r and height h is

V = πr²h.  Here we need to calculate the diameter after having found the radius.  Solving V = πr²h for r², we get:

           V

r² = -----------

         πh

Substituting the given values, we obtain for r² the following:

         145 units³

r² = ------------------------  = 15.6 units²

       3.14159(5 units)

Taking the square root of both sides, we get:

r = √15.60, or approx. 3.95 units.

The diameter is twice that, or approx. 7.90 units.

I am Lyosha [343]

Complete question :

Tim used the expression below, n³ where n represents side length, to determine the volume of a cube. Using this

expression, what is the volume of a cube with side length 3.5 inches? Show your work.

n?

Answer:

42.875 cubic inches

Step-by-step explanation:

Given that :

The formula to obtain the volume of a cube is n³ ; where n = side length of the cube.

The side length of a certain cube is given as = 3.5 inches.

The volume of the cube is calculated thus :

Volume = n³ = 3.5³

Volume = (3.5 * 3.5 * 3.5) inch³

Volume = 42.875 in³

Which of the aaa-values satisfy the following inequality?
mina [271]

Answer:

a = 3

Step-by-step explanation:

When you add the given value for a with 7, the resulting answer must be less than 11.

In this case, if: a = 3

Plug in 3 for a in the equation:

7 + a < 11

7 + 3 < 11

10 < 11 (True).

A) a = 3 is your answer.

Jason's two test scores in English are 87 and 91. What must he score on the third test to get an average test score of 92 or bet
irga5000 [103]

You first find the average of the first two test scores. When you find the average, you add the two numbers together and then divide by two which gives you 89. You then plug in different scores above the number 89 and find the average of those (89 and x) to see which gives you an average of 92. It’s mostly a guess and check type of problem.
