![]() ![]() In cases where an object has a shape that is not typical, it is more difficult to determine its volume, and the methods for doing so will not be described on this page. The surface area formula for a sphere is 4 x x (diameter / 2) 2, where (diameter / 2) is the radius of the sphere (d 2 x r), so another way to write it is 4 x x radius 2.Visual on the figure below: A spheres surface area can be calculated just by knowing its diameter, or radius (diameter 2 x radius). Also, if the object has a shape that is made up of a few typical shapes, we can calculate the volume by finding the sum of the volumes of each shape. Given that the object whose volume we want to determine is a typical shape, we can calculate its volume by plugging in its measurements into well-known formulas. The amount of water that the aquarium can hold is the volume (sometimes referred to as capacity) of the container. 'Volume equals pi times radius squared times height.' Now you can solve for the radius: V x r2 x h <- Divide both sides by x h to get: V / ( x h) r2 <- Square root both sides to get: sqrt (V / x h) r. The Volume of a Rectangular Prism Calculator is used to help you find the volume of a rectangular prism (Step by Step). ![]() For example, an aquarium with a length of 3 meters (m), a width of 0.5 m, and a height if 1.5 m can only hold a specific amount of water (2.25 m 3) before it overflows. The formula for the volume of a cylinder is: V x r2 x h. ![]() The volume of an object is the amount of three-dimensional space that the object takes up. Click the desired tab to select the shape whose measurements you want to calculate. This volume calculator computes the volume of a cylinder, cone, sphere, prism, or pyramid. ![]()
