Depending upon the spherical part in question, methods of the calculus would ordinarily be required to calculate the volume. However, there is an excellent website called Dr. Math that gives formulas for computing the volume of many kinds of spherical parts -- caps, sectors, segments, zones. These formulae are parameterized answers to the calculus problems you might otherwise have been forced to solve. The Dr. Math formulas are right here: http://mathforum.org/dr.math/faq/formulas/faq.sphere.html
Calculate the volume of a full sphere, then divide that by 2.
Volume of a sphere = 4/3*pi*radius3 in cubic units.
mass over volume
A sphere with a radius of 5 has a volume of: 523.6 cubic units.
shove it up your a@@ and eat it.
1) Calculate the area 2) Calculate the volume 3) Divide the area by the volume to get the ratio
Vol = 4/3*pi*r^3 where r is the radius of the sphere.
643,8.1033 (pm)3
A sphere volume = 4/3 pi r cubed
Circles do not have volume because they are 2 dimensional. The area of a circle is PI*r2 . A sphere has volume and the volume of a sphere is 4/3*pi*r3 where r is the radius.
2,570 cubic cm
Vol = 4/3*pi*r3 so given the volume, you can calculate the radius. Height of sphere = 2*radius.
