Question

PLEASE HELP :( will give medal

Answer 1

What is the equation for the volume of a cone?

Answer 2

great, what information do we have and what information do we need?
find diameter which is 2xradius
given V=29.31, h=7 and pi=3.14

Answer 3

4 inches and r u doing flvs

Answer 4

@plainntall so i need to find the radius first?
@Nora4Christ thanks but i need to learn how to do this and not just get an answer. But yeah im doing FLVS, the online textbooks are crap

Answer 5

me 2.. and ill give an example

Answer 6

solving the equation for r and then substituting the numbers is a good way to do it

V = (1/3)pi*r^2h ;divide both sides by everything but r^2 to start solving for r

Answer 7

the question: A billiard ball has a volume of 5.96 cubic inches. Find the radius of the ball.
Answer and explanation: he formula for the volume of a sphere is:

V = (4/3)πr³

plug in 5.96 for V and solve for r:

5.96 = (4/3)πr³

multiply both sides by (3/4):

4.47 = πr³

divide both sides by π:

r³ = 4.47/π

cube root both sides:

r = cube root of (4.47/π)

approximate using calculator:

r = 1.12474

approximately 1.125 inches

(or 1 1/8 inch)

that's it! ;) hope this helps
