Since the volume of a cone is pi times the radius squared times the height divided by 3, if you know the diameter, you simply divide by two to find the radius, which you then plug into the formula.

The surface area of a cone is equal to the curved surface area plus the area of the base: π r 2 + π L r , \pi r^2 + \pi L r, πr2+πLr, where r denotes the radius of the base of the cone, and L denotes the slant height of the cone.

The radius of a cone is the radius of its circular base. You can find a radius through its volume and height. Multiply the volume by 3. For example, the volume is 20.

['Surface Area. The surface area of a Torus is given by the formula – Surface Area = 4 × Pi^2 × R × r. Where r is the radius of the small circle and R is the radius of bigger circle and Pi is constant Pi=3.14159.', 'Volume. The volume of a cone is given by the formula – Volume = 2 × Pi^2 × R × r^2.']

The formula is π(r^2)*h, with r being the radius and h being the height. So the relationship between the radius and volume would be that the volume of a cylinder is the radius squared and multiplied by π and h.

The curved surface area of a right circular cone equals the perimeter of the base times one-half slant height. The total surface area equals the curved surface area of the base.

The two formulas that are useful for finding the radius of a circle are C=2*pi*r and A=pi*r^2. We use algebra skills in solving for our variable r. We know that the constant pi is always 3.14. Another word related to the radius is diameter, which is always twice the radius.

Calculate the volume of a square or rectangular cube using the formula V = l × w × h. Begin by multiplying length × width × height. So if your cube is 5 cm long, 3 cm wide and 2 cm tall, its volume is 5 × 3 × 2 = 30 cubic centimeters.
