  • At first glance, calculating the area of a triangular, sloped surface seems like an extremely tricky task. The average person knows that area is usually calculated by multiplying the length of an object by its width, but for a sloped surface one of those measurements is difficult to determine exactly, even with the help of a ruler or measuring tape.

Since, for every cross-section, the ratio of the area of the circle to the area of the square is equal, namely: PI*r^2 PI ----- = --- (2*r)^2 4. then the ratio of the volume of the sphere to the volume of the space common to both cylinders (the answer you want!) must also be PI/4. This works out to: This calculator computes volume and surface area of spherical cap and spherical segment. A spherical segment is the solid defined by cutting a sphere with a pair of parallel planes. It can be thought of as a spherical cap with the top truncated, and so it corresponds to a spherical frustum.

This calculator is designed to give all of the mathematical values of a circle and sphere from only one entered data value. Enter any of the four circle values, area, radius, diameter or circumference, click on Calculate and the other three values are returned in full (up to 18 decimal places) and maximum 3 decimal place rounded values. Jun 01, 2008 · The radius of the hemisphere is the same as the sphere. So the volume formula for the sphere is V = 4/3pi*r^3 Since the volume is 48.5 = 4/3pi*r^3 you want to solve for r by: 1: Multiply by 3/4 on both side to get rid of 4/3 2: Divide by pi on both side 3: Take cube root on both side. You can input cube root as the exponent of 1/3 Cheers The formula for the surface area of a sphere is: 4 π \pi π r^2. To find out the hemisphere's surface area, we can divide this formula by 2 which gives us: 4 π \pi π r^2/2. But don't forget that the bottom of the hemisphere now also becomes a surface and will have its own surface area.
