Answer:
84 square feet as law of prism = perimeter of traingle ×length
My answer is 12 because I subtract 36 from 24 and got 12
Complementary means the two angles add up to 90 degrees. Do 90 - 79 to find the other angle.
It's 11 degrees.
Answer: Option C.
Step-by-step explanation:
Use the formula for calculate the volume of a cone:

Where r is the radius and h is the height.
Volume of the cone A:

Volume of the cone B:
If the height of the cone B and the height of the cone A are the same , but the radius of the cone B is doubled, then its radius is:

Then:

Divide
by
:

Therefore: When the radius is doubled, the resulting volume is 4 times that of the original cone.
