Step-by-step explanation:
The volume of a pyramid with hight and base is 1/3 the volume of a rectangleular prisim with the same height and base
also the volume of a cone is 1/3 the volume of a cylinder with same height and base so
just fun facts to know (helpful)
so volume of cylinder=1/3 times height tiimes pi times radius^2
subsitute
use pi=3.14
height=12
radius=6
volume=1/3 times 12 times 3.14 times 6^2
volume=4 times 3.14 times 36
volume=452.16 cubic meters
the naswer is the top left choice
The left and right sides make up the parallel sides of the trapezoid. The top and bottom would be congruent but not parallel.
Answer:
Yes, see below.
Step-by-step explanation:
Convert the equation to vertex form to find the maximum height:
h = -16t2 + 64t + 5
= -16(t^2 - 4t) + 5
= -16 [(t - 2)^2 - 4] + 5
= -16( t - 2)^2 + 64 + 6
= -16(t - 2)^2 + 69.
So the maximum height the rock reaches is 69 feet.
This height is reached at 2 time seconds.
