Calculating Volumes of Geometric Shapes
- The volume of a cylinder with a radius of 4 inches and a height of 6 inches is calculated using the formula V = πr²h, resulting in 96π cubic inches or approximately 301.6 cubic inches.
- To find the volume of a sphere with a surface area of 256π square feet, the radius is determined to be 8 feet, leading to a volume of 2048π/3 cubic feet or approximately 2144.7 cubic feet.
- The volume of a cone with a radius of 5 centimeters and a height of 8 centimeters is found using the formula V = (1/3)πr²h, yielding 200π/3 cubic centimeters or approximately 209.44 cubic centimeters.
- The volume of a rectangular prism measuring 4 feet by 5 feet by 6 feet is calculated by multiplying the dimensions, resulting in a volume of 120 cubic feet.
- By utilizing the longest diagonal of a cube, which is 12.1243 centimeters, the side length is determined to be 7 centimeters, leading to a volume of 343 cubic centimeters.
