How do you find the volume of a sphere?
\frac{4}{3}\pi r^2
\frac{4}{3}\pi r^3
\frac{3}{4}\pi r^3
\frac{4}{3}\pi r^3h
2
What is the arc length formula?
l=C\left(\frac{360}{x}\right)
l=C\left(\frac{x}{360}\right)
l=\pi r\left(\frac{x}{360}\right)
l=2\pi d\left(\frac{x}{360}\right)
3
How do you find the volume of a prism?
Find the area of the faces, and then add them all together.
Listen to the prism very closely.
Multiply the area of the base by how tall/long the prism is.
Base times Length, duh.
4
What does SOH mean?
\sinθ=\frac{hypotenuse}{opposite}
\sinθ=\frac{adjacent}{hypotenuse}
\sinθ=\frac{hypotenuse}{adjacent}
\sinθ=\frac{opposite}{hypotenuse}
5
How do you find the volume of a pyramid?
\frac{4}{3}\pi r^3
Pyramids are abandoned alien spaceships with infinite interior volume.
Multiply the area of the base by height and then divide by 3.
\frac{1}{3}Bh
6
What does CAH mean?
\tanθ=\frac{opposite}{hypotenuse}
\tanθ=\frac{adjacent}{opposite}
\tanθ=\frac{opposite}{adjacent}
\tanθ=\frac{hypotenuse}{adjacent}
7
What is the equation of a circle?
\left(x-h\right)^2+\left(y-k\right)^2=r^{ }
\left(y-h\right)^2+\left(x-k\right)^2=r^2
\left(x-h\right)^2+\left(y-k\right)^2=r^2
\left(x+h\right)^2-\left(y+k\right)^2=r^2
8
How do you find the volume of a cone?
The volume of the cone depends on how many scoops you get.
\frac{1}{3}Bh
Multiply the area of the base by height and then divide by 3.
\frac{1}{3}\pi r^2h
9
What does some old hippy have to do with geometry?
SOH CET EOI
SAH COH TAO
SOH CAH TOA
SOH CAH TAO
10
What does CAH mean?
\cosθ=\frac{hypotenuse}{adjacent}
\cosθ=\frac{adjacent}{hypotenuse}
\cosθ=\frac{hypotenuse}{opposite}
\cosθ=\frac{opposite}{hypotenuse}
11
What is the formula to find the slope of a line?
m=\frac{\left(x_2-x_1\right)}{\left(y_2-y_1\right)}
m=\frac{\left(y_2-y_1\right)}{\left(x_2-x_1\right)}
m=\frac{\left(x_2+x_1\right)}{\left(y_2+y_1\right)}
m=\frac{\left(y_2+y_1\right)}{\left(x_2+x_1\right)}
12
How do you calculate the area of a sector?
The area of the circle multiplied by the relevant angle divided by 360
A=\pi r^2\left(\frac{x}{360}\right)
A=\pi r^3\left(\frac{x}{360}\right)
The area of the sector is classified information.
13
When using SOH CAH TOA, what mode should your calculator be set to?
Degree Mode
Radian Mode
Geometry Mode
Performance Mode
14
Why do you need to memorize these formulas?
If I don't, Mr. Hawkins will literally have a brain anerism.
It is neccessary to answer several of the EOC questions.
The EOC formula sheet is not super helpful, so I have to help myself.
I don't. Memorizing formulas is just a conspiracy desgined to brainwash us.
15
How do you find the volume of a cylinder?
Multiply the area of the base by how tall/long the cylinder is.
\pi r^2h
2\pi r^2
Cylinders don't talk. The volume is always zero.
