Question

Could any one say for me the volume and the surface for "Pyramid, Cone and Sphere"

Answer 1

Answer:

Pyramid: In fact, the volume of any pyramid is one-third the area of the base times the height. Finding the surface area of a pyramid is done by first finding the area of the base and the area of each lateral face. … Lastly, the surface area of a pyramid is the sum of the area of the base and the lateral area!

Cone: a volume of 4 3 π r 3 \frac{4}{3} \pi r^3 34πr3 and a surface area of 4 π r 2 4 \pi r^2 4πr2.

Sphere: A cone is essentially a pyramid with a circular base. The volume of a pyramid is given by Vpyramid=Abase⋅h3. Since the area of the base of a cone is πr2, the formula for the volume of a cone is Vcone=πr2h3.
