It depends on what you mean by base. The radius or the diameter of the circle? If the diameter is 8 cm it's 502.4. If the radius is 8 cm it's 2009.6.
volumn of a square pyramid = (1/3)*(base^2)*(height)
Area = Base * vertical height = 8*14 = 112 cm2
35cm2
A+ = 28 centimeters cubed
384 cubic centimeters.
Volume of a pyramid = 1/3*base area*height Height of a pyramid = (3*volume)/base area
volumn of a square pyramid = (1/3)*(base^2)*(height)
A cylinder with a radius of 5 centimeters and height of 9 centimeters
(1/2)base*height = .5(10)(15) = 75
Area = Base * vertical height = 8*14 = 112 cm2

A+ = 28 centimeters cubed
384 cubic centimeters.
Area = Base * (vertical) height = 11 * 3.5 sq cm = 38.5 sq cm.
Area of a triangle is 1/2 * base * height, so .5 * 5.5 * 8.8 = 24.2
