Question

HELP ASAP!! WILL MARK AS BRAINLIEST IF ANSWERED FAST!!

Answer 1

Cylinder: a = 2πrh+2pi• πr^2
Sphere: a = 4πr^2
Rectangular prism: a = 2(wl+hl+hw)

Sorry that's all I know :(

Answer 2

The surface area is the area that describes the material that will be used to cover a geometric solid. When we determine the surface areas of a geometric solid we take the sum of the area for each geometric form within the solid.

The volume is a measure of how much a figure can hold and is measured in cubic units. The volume tells us something about the capacity of a figure.

A prism is a solid figure that has two parallel congruent sides that are called bases that are connected by the lateral faces that are parallelograms. There are both rectangular and triangular prisms. To find the volume of a prism (it doesn't matter if it is rectangular or triangular) we multiply the area of the base, called the base area B, by the height h.

V=B⋅hV=B⋅h

A cylinder is a tube and is composed of two parallel congruent circles and a rectangle which base is the circumference of the circle.
