Formula for finding volume of a circle
WebVolume Many three-dimensional solids can be generated by revolving a curve about the -axis or -axis. For example, if we revolve the semi-circle given by about the -axis, we obtain a sphere of radius . We can derive the familiar formula for the volume of this sphere. Finding the Volume of a Sphere Consider a cross-section of the sphere as shown. WebApr 24, 2024 · The Math / Science. The formula for the volume of a semicircle is: V = ½•π•r²•h. where: V is the volume of the semicircle. h is the height of the semicircle. r is the radius of the semicircle. Volume of a uniformed shaped object such as an octagon column is derived by the following formula: Volume = Area • Height.
