Answer:
Height of the cylinder is 1ft
Step-by-step explanation:
Data ;
Volume = 314ft³
Assuming radius = 10ft
Height = ?
π = 3.14
Volume of a cylinder = πr²h
r = radius
h = height of the cylinder
Vol = πr²h
314 = 3.14 × 10² × h
314 = 314h
Solve for h,
h = 314 / 314
h = 1ft
The height of the cylinder is 1ft.
The answer is 27 hope it helps
Answer: -1.9b + 7.8
Step-by-step explanation:
since there are only two like terms you need to combine 1.3b and -3.2b
hmmm. well did u try searching it on the net first???
Answer:
t = 4 s
Step-by-step explanation
We can infer the origin from the t⁰ term of the quadratic as being 192 feet above the ground. Initial velocity is 16 ft/s from the t¹ term, gravity is -32 ft/s² from the t² term
0 = -16t² + 16t + 192
0 = -t² + t + 12
0 = t² - t - 12
0 = (t - 4)(t + 3)
so either
t - 4 = 0
t = 4 s
or
t + 3 = 0
t = -3 s which we ignore as it occurs before the ball is released.
