What is the volume of a cylinder with a height of 3 feet and a radius of 4 feet use 3.14 for pi

Vlad1618 [11]

Answer:

$\large\boxed{V\approx150.72\ ft^3}$

Step-by-step explanation:

The formula of a volume of a cylinder:

$V=\pi r^2H$

r - radius

H - height

We have the height H = 3ft and the radius r = 4ft. Substitute:

$V=\pi(4^2)(3)=\pi(16)(3)=48\pi\ ft^3$

$\pi\approx3.14$

$V\approx48(3.14)=150.72\ ft^3$

What is the average rate of change between f (1) and f (5) in the function f (x) = x2 - x - 6 ?

NISA [10]

Answer:

${ \tt{average = \frac{f(1) + f(5)}{2} }} \\ \\ = { \tt{ \frac{( {1}^{2} - 1 - 6) + ( {5}^{2} - 5 - 6) }{2} }} \\ = \frac{ - 6 + 14}{2} \\ \\ = { \tt{4}}$
