What is the volume of a sphere with radius of 2 m?
Volume of a sphere is 4/3 pi times the cube of its radius.
What is the volume of a sphere that has a radius of 2 cm?
The rule for the volume of a sphere is:4piR^3/3where R is the radius.So if the radius is 2,V = (4pi x 2^3) /3V = (4pi x 8) /3V = 32pi / 3V = 33.51cm^3
What is the volume of a sphere of radius 7cm?
The volume of a sphere is given by the formula V =⁴⁄ ₃πr3The volume of a sphere with radius 7cm = ⁴⁄ ₃π73 = 1436.76 cm3 (to 2 dps)
What is the circumference of a sphere whose volume is 904.7786842 cubic cm?
First we have to find the radius of the sphere because the circumference is 2*pi*radius. 4/3*pi*radius3 = 904.7786842 cubic cm With your calculator multiply both sides by 3 and then divide both sides by 4*pi: radius3 = 216 Cube root both sides: radius = 6 cm Circumference = 2*pi*6 = 37.69911184 or 38 cm to the nearest cm.
How can you prove that the volume of a sphere is equal to the volume of a cylinder provided their radii are equal and the height of the cylinder is equal to the diameter of the sphere?
I'm quite sure this is impossible to prove, because the volume of a sphere is not equal to the volume of a cylinder with the same radius and height equal to the sphere's diameter. This can be shown as: Volume of sphere = (4*pi*r3) / 3. Volume of cylinder = pi*r2*h. Here, the height, h, of the cylinder = d = 2r. So, the volume of the cylinder = pi*r2*2r = 2*pi*r3, which obviously does not equal the volume of the sphere. The volume of half a sphere (with radius r) is equal to the volume of a cylinder(whose height is equal to its radius, r) minus the volume of a cone with the same height and radius. Therefore, the volume of a sphere is just double that. If you follow the nearby link, you can see a nice demonstration of that.
