olga_2 [115]

Answer:

$87.125\pi in^{2} or 87\frac{1}{8}\pi in^{2}$

Step-by-step explanation:

Given Surface Area of Cylinder = $2\pi rh+2\pi r^{2}$ ,

and also given r = 4.25 inches and h = 6 inches.

Let's Substitute r and h into the formula to find the total surface area.

Surface Area of Cylinder = $2\pi (4.25)(6)+2\pi (4.25)^{2} \\=51\pi +36.125\pi \\=87.125\pi in^{2} or 87\frac{1}{8} \pi in^{2}$

Simplify 26-18b+11(b-3)

xxMikexx [17]

Answer:

<u>-7b-7</u>

Step-by-step explanation:

First you have to distribute 11 throughout the parentheses.

$26-18b+11(b-3)\\26-18b+11b-33$

Now we can combine like terms. (-18b, 11b, -33, 26)

$-18b+ 11b$ and $-33+26$

$-7b$ $-7$

This is your simplified answer for your expression.

<u>-7b-7</u>
