Math help..?

Question

What are the equations to find...

The area of:
A. Circle
B. Square
C. Triangle

The volume of:
A. Circle/Cylinder
B. Sqaure/Cube
C. Triangle/Prism


Thanks for any help, I appreciate it.

Also, the surface areas for:
A. Circle/Cylinder
B. Square/Cube
C. Triangle/Prism

Too many great answers, I will put it into voting.

Answer 1

Area of a circle = pi * radius^2
Area of a Square = L*W
Area of a Triangle = 1/2b*h

Volume of a Circle = 4/3 pi r^3 (I think)

Sorry, rest I am not sure of!

Answer 2

Circle:
pi r^2 where r is the radius

Square
l^2 where l is the length of one side

Triangle:

1/2 b h where b is the base and h the height of the triangle

Cylinder:
pi r^2 h where r is the radius and h the height

Cube:
l^3 where l is the length of one side

Prism:
A h where A is the area of the base and h the height

Answer 3

The Area ones are:
Circle= pr2
Square= width x height
Triangle= 1/2 base x height

Answer 4

The area of:
A. Circle: (pi)(r^2)
B. Square: (side)^2
C. Triangle: (1/2)(base)(height)

The volume of:
A. Sphere: (4/3)(pi)(r^3)
B. Cylinder: (pi)(radius^2)(height)
C. Cube: (side)^3

Answer 5

Area of:
A. circle: pi*r^2
B. square: s^2 (s= side)
C. triangle: 1/2bh (b= base h= height)

Volume of:
A. cylinder: pi*r^2*h (h = height)
B. Cube: s^3 (s = side)
C. Triangular Prism: 1/2lwh (l= length w= width h= height)


Hope this helped!

Answer 6

circle= pi r^2
square= s^2
tiranle= 1/2 bh


cylinder = Bh
cube= Bh
prism= Bh
where B is the area of the base and h is the height of the solid.

Answer 7

A. pi times the radius squared
B. side squared
C. 1/2 base times height

A. pi times the radius squared times the height (cylinder)
B.length times width times height (cube)
C. 1/2 width times length times height (prism)

Answer 8

area
A. pi r ^2
B. side x side
C. 1/2 x base x height

Volume
A. base x height
B. side x side x side
c. 1/3 area of base triangle x height

Answer 9

im not sure! sorry
