To derive the standard formula of a circle, a radius r is constructed as the hypotenuse of a right triangle as shown.

what are the lengths of the sides of the right triangle that is formed? check all that apply.

h
k
h – k
x – h
x – y
y – h
y – k

Find the measure of the interior angles of the following regular polygons: a triangle, a quadrilateral, a pentagon, an octagon, a decagon, a 30-gon, a 50-gon, and a 100-gon.

How do you create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1?

Abucket of paint has spilled on a tile floor. the paint flow can be expressed with the function p(t) = 6(t), where t represents time in minutes and p represents how far the paint is spreading. the flowing paint is creating a circular pattern on the tile. the area of the pattern can be expressed as a(p) = 3.14(p)^2 part a: find the area of the circle of spilled paint as a function of time, or a[p(t)]. show your work. part b: how large is the area of spilled paint after 8 minutes? you may use 3.14 to approximate pi in this problem.
