Use the net below to determine the surface area of the cylinder. (Use 3.14 for Tr.)

baherus [9]

Option D:

Surface area of the cylinder = 753.6 cm²

Solution:

<u>To find the surface area of the cylinder:</u>

Given data:

Radius of the cylinder = 6 cm

Height of the cylinder = 14 cm

The value of π = 3.14

Surface area of the cylinder = $2 \pi r^{2}+2 \pi r h$

$=2\times 3.14\times6^2+2\times3.14\times 6 \times14$

= 226.08 + 527.52

= 753.6 cm²

Surface area of the cylinder = 753.6 cm²

Option D is the correct answer.

Graph 3x+y=-10 -x+3y=0

nikdorinn [45]

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

We have the equations in the standard form. Convert to the slope-intercept form:

$3x+y=-10$ <em>subtract 3x from both sides</em>

$y=-3x-10$

$-x+3y=0$ <em>add x to both sides</em>

$3y=x$ <em>divide both sides by 3</em>

$y=\dfrac{1}{3}x$

-----------------------------------------------------

We need only two points to plot a graph of each function.

$y=-3x-10$

for x = 0 and for x = -3:

$y=-3(0)-10=0-10=-10\to(0,\ -10)\\\\y=-3(-3)-10=9-10=-1\to(-3,\ -1)$

$y=\dfrac{1}{3}x$

for x = 0 and for x = -3:

$y=\dfrac{1}{3}(0)=0\to(0,\ 0)\\\\y=\dfrac{1}{3}(-3)=-1\to(-3,\ -1)$

Look at the picture.

CaHeK987 [17]

Answer:

7/16

Step-by-step explanation:

assume she had 8/8 units of sea shells, she then left 1/8 at home

so: 8/8-1/8=7/8

so she has 7/8 units of shells still at home

and she gives half to her friend

so: 7/8*1/2=7/16

She gave 7/16 of the original amount of shells she had to her friend

How to factorize the following expression?<br>pqr + pr + q + 1

Sveta_85 [38]

<h3>Answer: (pr + 1)(q + 1)</h3>

===============================================

Work Shown:

Use the factor by grouping method to get the following.

pqr + pr + q + 1

(pqr + pr) + (q + 1)

pr(q + 1) + 1(q + 1)

(pr + 1)(q + 1)

We can use the FOIL rule, distribution, or the box method to expand out (pr+1)(q+1) to get the original expression again. This helps confirm the answer.
