Find the surface area of the cylinder with diameter 20 in. and height 2 in. Use 3.14 for
pi.
Answers
Answer:
[tex]\boxed {\boxed {\sf SA= 753.6 \ in^2}}[/tex]
Step-by-step explanation:
The surface area of a cylinder is found using this formula.
[tex]SA=2 \pi rh+ 2 \pi r^2[/tex]
We know the diameter is 20 inches and the height is 2 inches. We must find the radius.
The radius is half the diameter. r= d/2 r= 20 in /2= 10 inNow we know that:
[tex]r= 10 \ in \\h= 2 \ in[/tex]
Substitute the values into the formula. Also, plug 3.14 in for pi.
[tex]SA=2 (3.14)(10 \ in)(2 \ in)+ 2 (3.14)(10 \ in)^2[/tex]
Solve according to PEMDAS: parentheses, exponents, multiplication, division, addition, and subtraction.
Solve the exponent.
(10 in)²= 10 in * 10 in= 100 in²[tex]SA=2 (3.14)(10 \ in)(2 \ in)+ 2 (3.14)(100 \ in^2)[/tex]
Multiply all the numbers together.
[tex]SA=2 (3.14)(20 \ in^2)+ 2 (3.14)(100 \ in^2)[/tex]
[tex]SA=125.6 \ in^2+628 \ in^2[/tex]
Add.
[tex]SA= 753.6 \ in^2[/tex]
The surface of the cylinder is 753.6 square inches.

Peter represents the living room and kitchen of his house using the scale model shown below. One inch in the scale model corresponds to a
length of 10 feet in the actual room.
3 in
Living Room
Narrow Section
Kitchen
15 in
-2 in
What are the dimensions of the actual kitchen?
Answers
Answer:
15x20
Step-by-step explanation:
If you look closely in the question, it says one inch is 10 feet in the actual room. So what you would do is take the measurements and multiple by 10. All sides of the room are 3 inches but what the trick is, it asks you for the dimensions of the kitchen. So you would multiple 2x10 and 1.5 x 10 :)!

Complete the equation of the line whose slope is -5/3
and y-intercept is (0, -2).
Answers
Answer:
these are tough, it takes a lot of practice to get used to these, sooo
Step-by-step explanation:
we know the slope, m= -5/3, and we're given a point so use the point slope formula
y= mx + b
the point we are given is in this form (x,y)
then plug the information into our point slope formula
y = (-5/3) x + (-2)
y = -5x/3 -2

Answer:

Step-by-step explanation:
=4
=8
5x²-44x + 130 + 30 - 16x = 0
5x² -60x + 160 = 0
devide by 5
x² - 12x + 32 = 0
(x-4) (x-8) = 0
x-4 = 0 then x = 4
x-8 = 0 then x = 8
so x=4 and x=8
