B. 12.7
The slant height of a cone can be calculated using the Pythagorean theorem.
Slant height (l) = √(radius^2 + height^2)
l = √(15^2 + 8^2)
l = √(225 + 64)
l = √289
l = 17
Therefore, the slant height of the cone is 17 cm.
A cone has a radius of 15cm and a height of 8cm. What is the slant height of the cone?
A.
17
