What the volume if the radius is 7?

The volume of a sphere whose radius is 7 cm is V = (4/3)*(pi)*r^3 or V = (28/21)^7^3 = 457.3333 cc.

How do you write the volume of a sphere in terms of pi?

Volume of a sphere: V = (4/3)πr.

What is the volume of this sphere 7cm?

Tutoring Math, Physics, and Economics. Well, the volume of a sphere is given by 4/3*pi*r^3. Setting r = 7, we get 4/3*pi*7^3 = 1436.75 ~= 1437 cm^3.

What is the volume of radius 7cm?

Summary: The volume of the sphere with a radius of 7cm is 1437.33 cm3 and the volume of the sphere with a radius of 0.63m is 1.05 m³.

What is Pi in sphere?

Radius – The radius of a sphere is the distance from the center to the surface. The diameter is always twice the distance of the radius. Pi – Pi is a special number used with circles and spheres. It goes on forever, but we will use an abbreviated version where Pi = 3.14.

How do you find the radius of a sphere in math?

The formula used to calculate the sphere radius is: r = ∛((3/4) · V / π) Symbols. r = Sphere radius; V = Sphere volume; π = Pi = 3.14159… Volume of Sphere. Enter the volume contained within a sphere. Radius of Sphere. This is the radius of a sphere that corresponds to the specified volume.

How do you calculate the volume of a full sphere?

The spherical cap volume appears, as well as the radius of the sphere. They are equal to 287 cu in and 4.2 in for our example. To calculate the volume of the full sphere, use the basic calculator. Enter the radius 4.2 in. Now you know, that fish tank has the volume 287 cu in, in comparison to 310.3 cu in for full sphere volume with the same radius.

What is a sphere in terms of pi π?

It will also give the answers for volume, surface area and circumference in terms of PI π. A sphere is a set of points in three dimensional space that are located at an equal distance r (the radius) from a given point (the center point). Units: Note that units are shown for convenience but do not affect the calculations.

What is the volume of a 5 inch sphere in cubic inches?

For example, if the radius of a sphere is 5 inches, using the second sphere volume equation results in 4/3 x 3.14159 x 5 3 = 4.1866 x 125 = 523.6 in 3 (cubic inches).
