Radius = Diameter ÷ 2
Radius = 10 ÷ 2 = 5
.
Volume = πr²h
Volume = π(5)² (20) = 500π cm³
.
Answer: 500π cm³
First, you are going to want to get the terms to the same power of 10 in scientific notation. Realize that
. Essentially, we have converted the
to a term with
. Now, we can subtract the values in each term that are not 10 as shown below:



Remember that we have to turn it back to scientific notation once we are done!

Our answer is the second choice,
. (This is the closest answer to
.)
I believe it’s D sorry if I’m wrong
You can find the slope and y-intercept, and make an equation in slope- intercept form and them just plug in the other x values in the equation.
a linear angle = 180 degrees
180-67 = 113
angle 1 = 113 degrees
