For Amanda’s birthday, Rhett made an amazing, cylindrical, chocolate cream
cheesecake. The radius and height of the cake were the same. Rhett cut the cake into 8 congruent slices and ate the first slice for quality control purposes.

Rhett then posed the following two questions to Amanda:

a) After removing my slice, is there more or less total surface area (top, bottom
and all exposed sides) in the remaining cake?

b) By what percentage, to 1 decimal place, has the remaining surface area
increased or decreased?

the ordered pairs for the given function are of the form

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3

hope this if needed hmu
