Answer:
12s.
Step-by-step explanation:
Given:
Hudson's velocity, Vh = 8.8 ft/s
Katie's velocity, Vk = 6.3 ft/s
Kate's head start distance, Dk = 30 ft
From the above, Katie and Hudson meet at th = tk = t
But, Dk = Dh + 30
Velocity = Distance/time
t × Vk = Dk
t × Vh = Dh
t × Vk + 30 = Dk
t × Vk + 30 = Vh × t
6.3t + 30 = 8.8t
t = 30/2.5
= 12 s
you use the formula: A=pi*r^2

Answer:
V = 1071.79 yd^3
Step-by-step explanation:
The volume of a cone is
V = 1/3 pi r^2 h where r is the radius and h is the height
We are given a diameter of 16 so the radius is 1/2 of the diameter or 8
The height is 16
V = 1/3 ( 3.14) (8)^2 ( 16)
V = 1071.78666 yd^3
Rounding to the nearest hundredth
V = 1071.79 yd^3
