Answer:
63°
Step-by-step explanation:
TSU = 180 - 117 = 63
Answer:
maybe it's 10.because c is 10,b is 10,and so as s.
hence s is 10 also.
Here you'll need to do some online research, using "area of a cone" as your search term. There is a formula! But it's complicated.
Once you've found this formula online, substitute 17 feet for r. The height of the cone has to be calculated from the slant height (these are not the same):
(slant height)^2 = (12 feet)^2 = r^2 + h^2, where h is the actual height of the cone.
The area of the base is pi*r^2, or pi*17^2 square feet.
