Question 253471: What is the slant height of a right circular cone whose lateral surface area is 66π units2 and whose radius is 6 units? Found 2 solutions by drk, Greenfinch:Answer by drk(1908) (Show Source):
You can put this solution on YOUR website! The lateral surface area has formula:
(i)
we know A = 66pi, r = 6. So,
(ii)
subtracting 36pi, we get
(iii) 30pi = 6pi(L)}}}
dividing by 6, we get
(iv) L = 5 units.
