That depends on how many units there are in the diameter of the sphere.

If the radius of the sphere is R units then the radius of the cross section is sqrt(R2 - 122)
Therefore the cross sectional area is pi*(R2 - 122) square units.
It is: cross-section area*length and measured in cubic units
A sphere with a radius of 2.4 units has a volume of 57.91 cubic units.
A sphere with a radius of 30 units has a volume of 113,097.34 cubic units.
A sphere's volume is measured in cubic units, not square units.
Volume in cubic units = cross-section area*length
If the radius of the sphere is R units then the radius of the cross section is sqrt(R2 - 32) Therefore the cross sectional area is pi*(R2 - 32) square units.
The cross section at this point forms a circle and its area is pi/32 which equals 9*pi square units. * * * * * Not quite. If the radius of the sphere is R units then the radius of the cross section is sqrt(R2 - 32) Therefore the cross sectional area is pi*(R2 - 32) square units.
Volume = Length*Area of cross-section So area of cross section = 1962.5/25 = 78.5 units If the cylinder has diameter d then area of cross section = pi*d2/4 So d2 = 4*Area/pi = 99.95 square units. Then d = sqrt(99.95) = 9.997 units of length.
It is: cross-section area*length and measured in cubic units
The volume of a sphere with a radius of 21 units is: 12,348 units 3
A sphere with a radius of 2.4 units has a volume of 57.91 cubic units.
A sphere with a radius of 3 units has a volume of 113.1 cubic units.
A sphere with a radius of 30 units has a volume of 113,097.34 cubic units.
A sphere's volume is measured in cubic units, not square units.
Volume in cubic units = cross-section area*length
r = 2.821 units
Section Modulus is moment of inertia divided by distance from center of gravity to farthest point on the cross-section or I/c. The units of Moment of Inertia is distance^4 so the units of section modulus is distance^3 ( distance cubed ). So if your units are in meters: I/c = (m^4)/(m) = m^3
