Aright triangle whose hypotenuse is startroot 7 endroot7 m long is revolved about one of its legs to generate a right circular cone. find the radius, height, and volume of the cone of greatest volume that can be made this way.
the answer is 0.
y = 11/4 or 2 3/4 units.
perimeter = 4 * length of 1 side
= 4(y + 11) , so
4(y + 11) = 55
4y + 44 = 55
4y = 11
y = 11/4 (answer).
diameter = 256 after 8 hours.
at time 0 the diameter is 1, at time 1 hour the diameter is 2, at time 2 hours the diameter is 4 and so on.
the equation of the graph is d = 2^t where d = the diameter and t = time in hours. this is exponential growth.
so after 8 hours the diameter = 2^8
= 256 (answer).
