Question

How do you find the slant height of a cone whose height is 8 feet and whose diameter is 16 feet.

Answers

Ms. Sue
Study this diagram and use the Pythagorean theorem.

Remember that the radius of this circle's base is 8 feet.

Ms Sue could you give me a little more help I've never done this kind of problem.
Ms. Sue
Did you look at that diagram?

Pythagorean Theorem:
a = length of base
b = height
c = slant height (hypotenuse)

a^2 + b^2 = c^2
8^2 + 8^2 = c^2
64 + 64 = c^2
128 = c^2
11.31 = c
