Answer:
Step-by-step explanation:
Area of circle:
<em>area = π · r · r</em>
<em>Radius= </em>
= 8
= 200.96 
<em></em>
This creates a cone! :) the formula for volume of it is 1/3 pi R^2 (h) just in case!
Answer:
She should ski on Slope B because it is steeper
Step-by-step explanation:
Slope A
We need to find the "slope"
15/24 = 5/8
Slope B
12/16 = 3/4
To compare, we need a common denominator
5/8 3/4*2/2
5/8 6/8
<
Slope B is steeper because the slope is greater
She should ski on Slope B because it is steeper
