Volume of a cylinder = pir^2h

Plug the given values into the equation:
pi4^2*3

Evaluate
pi16*3

The volume of the cylinder in terms of pi is 48 pi units cubed.

For an exact answer, use 3.14 for pi and evaluate:
3.14*4^2*3
3.14*16*3

The volume of the cylinder is 150.72 units cubed.

What is the answer to this question (3x3)+7-7=
exis [7]

Answer:

9

Step-by-step explanation:

Assuming x is the multiplication symbol, you would multiply 3 and the other 3 together. This leaves you with 9+7-7. Since 7-7=0 you can just get rid of both sevens completely. Now you are only left with 9.

The formula for the volume of a cone is V = jarh, where V is the volume, r is the radius, and h Is the heightWhat is the volume
olga nikolaevna [1]

Given:

The radius, r=4x

The height,

h=21xy^2

To find the volume of the cone:

The volume of the cone formula is,

V=\frac{1}{3}\pi r^2h

Substitute the values of r and h in the above formula we get,

\begin{gathered} V=\frac{1}{3}\pi\times(4x)^2\times21xy^2 \\ =\frac{1}{3}\pi\times16x^2\times21xy^2 \\ =\pi\times16x^2\times7xy^2 \\ =112\pi x^3y^2 \end{gathered}

Hence, the volume of the cone is

V=112\pi x^3y^2

Thus, the correct option is option D.

If m&lt;7 is 2x + 30 and m&lt;28 is 3x - 10, find the<br> following:
topjm [15]

Answer:

x = 32

m∠7 = 94

m∠8 = 86

m∠3 = 94

Step-by-step explanation:

(2x + 30) + (3x - 10) = 180

5x + 20 = 180

5x = 160

x = 32

m∠7 = 2(32) + 30 = 94

m∠8 = 3(32) - 10 = 86

<u>or</u>

m∠8 = 180 - 94 = 86

<u>m∠3 ≈ m∠7</u> (corresponding angles)
