How is finding the area of a parallelogram like finding the area of two congruent triangles?

If you look at either diagonal (line joining opposite angles) it forms 2 triangles that are identical, both in size and shape, but that are in different positions. So by finding the area of one using <u>base x height ÷ 2,</u> and then adding them together, you get the area of the polygon.
However, you will find that that would be the same as just doing <u>base x height</u>, so the area of a parallelogram is just that.

Solving system by substitution x=3y+11, 2x-3y=16

grin007 [14]

Input 3y+11 for x

2(3y+11)-3y=16
6y+22-3y=16
3y= -6
Divide by 3 to isolate y
y=-2

Now for x....

x=3(-2)+11
=-6+11
=5
x=5

The sphere area of a sphere is 200.96 square centimeters. What is the approximate volume of the sphere? Use 3.14 for pi. Round y

julsineya [31]

We are given

area of sphere is 200.96cm^2

it means that we are given surface area

so, we can use surface area formula

$S=4\pi r^2$

where S is surface area

r is radius

so, firstly we need to find radius or r

$200.96=4\pi r^2$

we can solve for r

$r=3.9989cm$

now, we can find volume

$V=\frac{4}{3} \pi r^3$

we can plug r

$V=\frac{4}{3} \pi (3.9989)^3$

now, we can find volume

$V=267.86cm^3$ .............Answer
