How calculate the volume of a sphere?

How calculate the volume of a sphere?

If the surface area is multiplied by the diameter, the volume will be obtained, in which every point on its surface is equidistant from its center. Mathematically, to calculate the volume of a sphere, the following formula is used: The volume of a sphere = 4/3 𝜋 r³, where r is the radius of the sphere.

What is the easiest way to find the volume of a sphere?

To calculate the volume of a sphere, use the formula v = ⁴⁄₃πr³, where r is the radius of the sphere. If you don’t have the radius, you can find it by dividing the diameter by 2. Once you have the radius, plug it into the formula and solve to find the volume.

What is the volume of a 12 in sphere?

12 cubed is 1728. Multiply that by 43 and you get 2304. If you substitute pi with 3.14, your final answer is 7234.56 .

How do you find the volume and area of a sphere?

Why is it 4 3 for volume of a sphere?

Volume of a sphere = 4/3 πr3 If you consider a circle and a sphere, both are round. The difference between the two shapes is that a circle is a two-dimensional shape and a sphere is a three-dimensional shape which is the reason that we can measure the Volume and area of a Sphere.

Why is sphere formula?

You will find a point equidistant from any point on the surface of a sphere. The longest straight line that passes through the center of the sphere is called the diameter of the sphere. It is twice the length of the radius of the sphere….Formulas of a Sphere.

How do you solve the volume of a sphere step by step?

How do you calculate the volume of a sphere without a calculator?

How do you calculate volume?

To find the volume of a box, simply multiply length, width, and height — and you’re good to go! For example, if a box is 5×7×2 cm, then the volume of a box is 70 cubic centimeters.

What is the volume of a 6 cm sphere?

The radius of a sphere is 6 centimeters. The volume of the sphere is 288π cm3.

How do you find the volume of a 12 cm?

1 Answer

1. V=43πr3.
2. Where r is the radius.
3. The diameter is 2×the radius.
4. radius=12cm2=6cm.
5. Plugging in this value of r.
6. V=43π(6)3=288π cm3.

What is the area of the sphere?

And the formula for the surface area of a sphere of radius R is 4*Pi*R2.

How do you find the volume of a sphere for kids?

How do you find volume from area?

Therefore, the formula to calculate surface area to volume ratio is: SA/VOL = surface area (x2) / volume (x3) SA/VOL = x-1 , where x is the unit of measurement. Below is a table showing how to calculate the surface area to volume ratio of some common three-dimensional objects.

What is 4 pi r squared?

The surface area of a sphere of radius r is 4pi r^2; its volume is 4/3 pi r^3. The acceleration required to keep an object in a circle of radius r at uniform speed v is a = v^2/r. The gravitational force between two objects of mass M and m separated by a distance r is G M m/r^2.

Why is the surface area of a sphere 4 pi r 2?
