Hey. Well, to answer this question, it is simply reversing the processes to find out what f is equal to. Essentially, you want to get f all by itself so we can find out what it is.

92 = 8(f+2)-4

92+4 = 8(f+2) ------ (Add 4 to both sides.)

96 = 8(f+2) ------- (ONE STEP CLOSER! Now, divide both sides by 8)

12 = f+2 ------(Looking good. Go on and subtract 2 from both sides.)

f = 10

Super cool. It's just to reverse whatever is done on the other side. If 2 is added on one side, go on and subtract it!

If you want to check, just go on and plug 10 into f in the original equation. It comes to 92!

How do you find the radius when given the volume and height?

Eduardwww [97]

Answer:

Calculate the area of the base (which is a circle) by using the equation πr² where r is the radius of the circle. Then, multiply the area of the base by the height of the cylinder to find the volume. SOO just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet. You can also use the circumference and radius equation.
