We are going to need to know the formula for the lateral surface area and volume of a cylinder in order to find our answers. Below are the equations:

$A_L = 2 \pi r h$

$V = \pi r^2 h$

$h$ is the height
$r$ is the radius

Using these formulas, we can solve these problems.

$A_L = 2 (3.14)(48.9) (84.3) \approx \boxed{25887.856}$

$V = (3.14) (48.9)^2 (84.3) \approx \boxed{632958.069}$

Consider the parametric curve:

11Alexandr11 [23.1K]

By the chain rule,

$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{\frac{\mathrm dy}{\mathrm dt}}{\frac{\mathrm dx}{\mathrm dt}}=\dfrac{4\sec t\tan t}{3\sec^2t}=\dfrac43\sin t$

When $t=\pi$ , we have

$\dfrac{\mathrm dy}{\mathrm dx}\bigg|_{t=\pi}=\dfrac43\sin\pi=0$

What is the gcf of 48 and 64

pantera1 [17]

First, make an organized list of the factors for each number. The common factors are 1, 2, 4, 8, and 16, and the greatest of these is 16. So, the greatest common factor or GCF of 48 and 64 is 16.
