Q&A for How to Calculate the Volume of a Sphere

If you know the surface area, solve the area formula for the radius, and use that to find the volume. Without the radius, you can't determine the volume.

Height is not included when measuring spheres, since usually they are congruent in all directions; it wouldn't be a necessity, because the radius is included.

Divide the diameter by 2, giving you the radius and continue from there.

Use the circumference formula (C=2πr) and rearrange it to solve for the radius (r=C/2π). Once you have the radius (r), you can use that value in the volume of a sphere formula (V = 4/3πr³).

Use the formula V= 4/3(3.14)(6^3). 6*6*6 = 216, V= 4/3*3.14*216, V=4*3.14*216= 2,712.96, 2,712.96/3 = 904.32. So the volume would be 904.32.

A cylinder's "curved" part is really just a rectangle with the one side as the circumference of the circular base of the cylinder. The other side is the height of the cylinder. Using the area of a rectangle formula, the surface area can then be written as: A = (2 * pi * r) * (h) = 2* pi * r * h. If you are including the circle ends of the cylinder, then add 2 * the area of the circle : 2 * pi * r * h + 2 * pi * r^2.

Use the volume formula to solve for the radius, then double the radius.

V=pi *a*b*h where "a" and "b" are the semi-major and semi-minor axes of the ellipse, and "h" is the height of the cylinder.

If you're asking only about the diameters, divide 18 by 32. That gives you a decimal number. Multiply it by 100 to get what percentage 18 is of 32. If you want to compare the two volumes, you'll have to cube each diameter and then perform the same division operation.

One billion times larger. 1,000 cubed is 1,000,000,000.

Theoretically there is only a point (and not an "area") that contacts the flat surface. In practice, there is no formula for finding the area that actually touches the surface.

4/3 πr³ means to multiply 4 by π (3.14), then multiply by the cube of the radius, then divide by 3.

Take the volume formula, set it equal to 30 ml, and solve for r.

Simply divide the value that you'll get from finding the volume of a sphere by 2. For example: (4/3 (3.14) (r^3)) 1/2. Find the value of the whole sphere first then divide by 2. But if only the half sphere's values are given, try this formula: V= (3.14) (r^2)

Using an average radius of 3,960 miles, the volume of the Earth is approximately 2.6 x 10^11 cubic miles.

The formula for the volume (V) of a sphere is V = 4/3 x pi x r³. So take your radius, 8 cm, and cube it (8 x 8 x 8), which gives 512. Multiply by pi, which is 1.608,4954, and multiply by 4/3, which gives 2.144,6605 cm³.

You have to work the formula around to isolate r. The formula is V = 4/3 x pi x r³. So r = [3 x (V/4 x pi)]^1/3. For your example, that would be 6.59 m.

The height is the diameter. The diameter is twice the radius. The radius is the cube root of the following quantity: 3 times the volume divided by 4π.

The amount of space within the sphere's surface; for example, the amount of air inside a basketball.

Volume = height multiplied by πr². First change the diameter to cm, and use half of it as the radius.

The "r" in the formula is 21cm so the formula is 4/3*pi*21^3 or 4/3*pi*9261=4/3*29094.2=38792.3, but halfway through the bowl means to divide by 2, so the answer is about 19396.1 ml.

The answer to your question involves integration and is too complicated to describe here. Search online for "derivation of formula for volume of a sphere."

First find the volume in cubic inches of a sphere with a 20-inch radius. There are 231 cubic inches in a US gallon, so divide the sphere's volume by 231 to find the equivalent number of gallons.

Sorry, no. That way is easiest.

Half the diameter is the radius. Plug that number into the volume formula above.

The two acute angles in a 3-4-5 triangle are 36.87° and 53.13°. You could round them off to 37° and 53°.

Then the volume will be expressed as (4/3)πx³, and you won't be able to find a specific number for the volume.

Area = πr² = π(d/2)² = π(1)² = 3.14 square meters.

If the tank is a cylinder, its volume is πr²h = (3.14)(45)²(183).

V = 100 = (4/3)πr³. (¾)(100/π) = r³. 23.87 = r³. The radius is the cube-root of 23.87. That's approximately 2.88.
