Algebra 1a: CST Review
WK5 (April 1): The area of a circle is defined as `A = πr^2`. The relationship between the radius `r` and the diameter `d` is:
`2r=d` or `d/2=r`
Remember on the 12-2 worksheet (page 101), that `π = 3.14`
WK4 (March 31): Plotting x-y graphs. X axis is horizontal and Y axis is vertical.
Plot the points on worksheet E-68 for the secret message!
WK3 (March 30): Remember, this only works for right triangles,
`c^2 = a^ + b^2` or `a^2 = c^2 – b^2` or `b^2 = c^2 – a^2`
`c = sqrt(a^2 + b^2)`
Worksheet D-73 is all about finding `c`, the hypotenuse!
