Volume of cylindersGiven the radius and h, the volume of cylinders can be found by using the formula: Volume_{cylinder} = Area of base × height = pi × r^{2}× h Use 3.14 for pi. Notice that the base of the cylinder is a circle and the formula to get the are is pi × r^{2} Example #1: Calculate Volume_{cylinder} if r = 2 cm and h = 5 cm Volume_{cylinder} = pi × r^{2}× h Volume_{cylinder} = 3.14 × 2^{2}× 5 Volume_{cylinder} = 3.14 × 4 × 5 Volume_{cylinder} = 3.14 × 20 Volume_{cylinder} = 62.8 cm^{3} Example #2: Calculate Volume_{cylinder} if r = 4 inches and h = 8 inches Volume_{cylinder} = pi × r^{2}× h Volume_{cylinder} = 3.14 × 4^{2}× 8 Volume_{cylinder} = 3.14 × 16 × 8 Volume_{cylinder} = 3.14 × 128 Volume_{cylinder} = 401.92 inches^{3} Fun game: Break spheres by matching balls with the same color
