You know the formula for calculating the lateral area of a cylinder with a radius r and height h is S=2*π*r*h
So we have S= 2*π*6*20= 240π
Have fun

Answer:

Option (b) is correct.

The lateral area for the given cylinder is $240\pi$ square units

Step-by-step explanation:

Given: A cylinder with radius 6 units and height 20 units.

We have to fine the lateral area for the cylinder with the given measurement.

The lateral area for the cylinder is given by $2\pi rh$

Put r = 6, h = 20

We have,

The lateral area for the given cylinder = $2\pi\cdot 6\cdot 20$

Simplify, we have,

The lateral area for the given cylinder = $240\pi$ square units

What is 2(12) 3/2 in its simpilist form

Tom [10]

Answer: 2/12 --> 1/6

3/2 --> 1 1/2

Step-by-step explanation:

2/12 can be simplified by dividing the top by 2 and the bottom by two. 2 is the GCF (greatest common factor) of both 2 and 12.

3/2 is a improper fraction so you have to make it a proper fraction. To do that you get 1 and 1/2. <-- this is for simplest form.

Hope this helped!

When p = 12, t = 2, and s = One-sixth, r = 18. If r varies directly with p and inversely with the product of s and t, what is th

bagirrra123 [75]

Answer:

$k = \frac{1}{2}$

Step-by-step explanation:

Given

$p = 12$

$t = 2$

$s = \frac{1}{6}$

$r = 18$

$r\ \alpha\ p\ * \frac{1}{s * t}$

Required

Find the constant of variation

From the question, the variation is as follows

$r\ \alpha\ p\ * \frac{1}{s * t}$

$r\ \alpha\ \frac{p * 1}{s * t}$

$r\ \alpha\ \frac{p}{s * t}$

Convert variation to equation

$r\ = k\frac{p}{s * t}$

Where k represents the constant of variation

Make k the subject of formula;

Multiply both sides by s * t

$r * s * t = k\frac{p}{s * t} * s * t$

$r * s * t = kp$

Divide both sides by p

$\frac{r * s * t}{p} = \frac{kp}{p}$

$\frac{r * s * t}{p} = k$

$k = \frac{r * s * t}{p}$

Substitute the values of p, r, s and t in the above equation

$k = \frac{18 * \frac{1}{6} * 2}{12}$

$k = \frac{6}{12}$

Divide numerator and denominator by 6

$k = \frac{1}{2}$

Hence, the constant of variation is; $k = \frac{1}{2}$
