Notes for finding Surface area and volume 1/17/17

Cylinder

Volume EQUATION=πr(2)h

http://www.ducksters.com/kidsmath/finding_the_volume_surface_area_of_a_cylinder.php

I used this source to help me gain a better understanding of how to fin the volume and surface area of a cylinder.

Terms of a Cylinder

Radius – The radius is the distance from the center to the edge of the circles at each end.

Pi-3.14

Height – The height or length of the cylinder.

Surface area EQUATION = 2πr(2) + 2πrh

Sphere

VolumEQUATION=4/3πr(3)

I used this source to help me gain a better understanding of how to fin the volume and surface area of a sphere.

Radius – The radius of a sphere is the distance from the center to the surface. It will be the same distance for a sphere no matter where it is measured from the surface.

Diameter – The diameter is a straight line from one point on the surface of the sphere to another that goes through the center of the sphere. The diameter is always twice the distance of the radius.

Pi = 3.14

Surface area EQUATION=4πr(2)

Cone

I used this source to help me gain a better understanding of how to fin the volume and surface area of a cone.

Terms of a Cone
Radius – The radius is the distance from the center to the edge of the circle at the end.

Height – The height is the distance from the center of the circle to the tip of the cone.

Slant – The slant is the length from the edge of the circle to the tip of the cone.

Pi-3.14

Surface area EQUATION = πrs + πr(2)
Volume = 1/3πr(2)h

Cube

Surface area EQUATION= 6 X (edge length) (2)

Volume EQUATION= (edge length) (3)
