Have you begun plugging in points?

malaya · Answer

nope

fortytherapper · Answer

How would it look if you plugged in all given information

V = (pi)(r)^2(h)

I'll start it off

Since V = 141.3

141.3 = (pi)(r)^2(h)

Can you finish it off?

wolf1728 · Answer

141.3 = 3.14159 * 3 * 3 * height
CAn you solve that for height?

malaya · Answer

I don't even know how to do this tbh : / @wolf1728

wolf1728 · Answer

Well, at least you could do the multiplication.

Okay I'll do it for you.

141.3 = 28.27433 * height

can you solve for height?

wolf1728 · Answer

height = 141.3 / 28.27433

malaya · Answer

Soo it would be 5.05 ? @wolf1728

wolf1728 · Answer

No - divide 141.3 by 28.27433

malaya · Answer

Well I put 5.05 and it said it was right but thats what i did @wolf1728

wolf1728 · Answer

Just to make sure, in the problem, does it state the volume is 141.3 and radius is 3?

malaya · Answer

yeahh

wolf1728 · Answer

Hmmm if the volume actually is 143.1 then the answer comes out to 5.06

malaya · Answer

its 141.3 @wolf1728

wolf1728 · Answer

Okay, then I don't know how the answer comes to 5.05.
You are determining the volume of a cylinder right?

malaya · Answer

Nope it just says find h @wolf1728

wolf1728 · Answer
