What is the exact volume of a cylinder 6in 9in

inna [77]

To find the exact volume of a cylinder, you must remember the rule - π r2 h

If 6 inches was the base (radius from the center of the cylinder to the edge) and 9 inches was the height, the equation would look like this -

π (6 squared in) (9 in)

Remember that the radius is squared so the equation would then look like

π (36 in) (9in)

Now you multiply 36 and 9 which would give you 324, then your equation would look like this

324 π

The final step is to multiply 324 by π which would be the volume of a cylinder.

What describes the number and type of the roots of the equation 4x+7=0

Kaylis [27]

Answer:

D : One Real Root

Step-by-step explanation:

Isolate "4x" by subtracting 7 from both sides.

So we get

4x = -7

Then we divide each side by 4 to get -7/4

x = -7/4 so there is only one real root.
