Radius = 2 inches
height = 8 inches .

Formula

$\bold { \purple {volume = \pi \: {r}^{2}h \: }}$

Lets assume pi to be 3.14

$v = 3.14 \times {2}^{2} \times 8 \\ \\ \\ v = 3.14 \times 4 \times 8 \\ \\ \\ v = 3.14 \times 32 \\ \\ \\ v = 1008.48 {in}^{2}$

Express the formula P=2L+2W in terms of the width,W. Use the formula to find the width when the perimeter is 70 and the length i

ozzi

Answer:

<h2>The width is 13</h2>

Step-by-step explanation:

From the question

P=2L+2W

where

L is the length

W is the width

To make W the subject move 2L to the left side of the equation

That's

2W = P - 2L

Divide both sides of 2 to make W stand alone

We have

$W = \frac{P - 2L}{2}$

when

P = 70

L = 22

W is

$W = \frac{70 - 2(22)}{2} \\ W = \frac{70 - 44}{2} \\ W = \frac{26}{2}$

We have the final answer as

Hope this helps you
