Whats the formula for a cirurference?

Answer 1

Volume=Ï€ r^2h

r^2=radius sqared

h=height

(do not calculate "Ï€ " into your equation)

example: DIAMETER is 12 and the height is 15

(the diameter = the radius x2, so the radius is 6 because it is half of 12)

V=Ï€ r^2h

V=Ï€ (6)^2(15)

V=540Ï€

Answer 2

Volume of any conic solid=1/3bh

Area of circle=Pi*r^2

Since the base (b) of the conic solid is a circle is the area of

the circle, substitute the second equation into the first one:

V=1/3*Pi*r^2*h

Answer 3

The formula to find the circumference of a circle is Pi X D where D is Diameter and Pi is 3.1416.

Answer 4

Circles don't have volume, but they do have area.

Answer 5

pi x r2 x thickness, with r (radius) and thickness being in the same units of length

Answer 6

Vc = Pi*r2h/3 where Vc is the volume of the cone, Pi is approximately 3.14159265358979323846264338327950288, r is the radius of the cone, and h is the height of the cone.

Answer 7

pi*r^2

so pi times (radius squared)

Answer 8

volume = {pi} x radius2 x height

Answer 9

pie x Diameter
