Answer:
32/ 3 pi ft^3
Step-by-step explanation:
The volume of a sphere is 4/3 pi r^3
V = 4/3 pi r^3
The radius is 2
V =4/3 ( pi) (2)^3
V = 4/3 pi (8)
= 32/ 3 pi ft^3
The answer is 0.52 s
The function is t = 0.005x² + 0.002x
x = 10
Substitute x into the function:
t = 0.005 * 10² + 0.002 * 10
t = 0.005 * 100 + 0.02
t = 0.5 + 0.02
t = 0.52 s
