The Surface area of the cylinder is 130π in terms of π. The formula for surface area of a cylinder is 2πrh + 2πr^2
2*π*5*8 + 2*π*5^2
2*π*40 + 2*π*25
2π*40 +2π*25
80π + 50π
130π

The surface area of a cylinder is 2*pi*r*h(side area)+2*pi*r^2(bases).

When you plug in the values: 2*pi*5*8+2*pi*25 = 80pi+50pi

Answer: 130pi

Answer:

Step-by-step explanation:

If all were measure 5, the perimeter would be 30. The perimeter is 4 more than that. Each side that is 6 instead of 5 adds 1 to the perimeter, so there are 4 sides of length 6.

What is an equation of the line that passes through the points (2, - 1) and (3, - 4)

lianna [129]

Answer:

y=-3x+5

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-4-(-1))/(3-2)

m=(-4+1)/1

m=-3/1

m=-3

y-y1=m(x-x1)

y-(-1)=-3(x-2)

y+1=-3x+6

y=-3x+6-1

y=-3x+5

Aiden has a smartphone data plan that costs $25 per month that includes 2 GB of data but will charge an extra $10 per GB over th

dem82 [27]

The amount Aiden would have to pay in a month where he used went over by x GB is (25 + 10x)

<h3>Equation</h3>

Cost if data plan (2gb) = $25
Additional cost per GB = $10
Number of additional gb = x

Total cost = 25 + 10x

If he used 2 GB over the limit

Total cost = 25 + 10(2)

= 25 + 20

= $45

Therefore, the amount Aiden would have to pay in a month where he used went over by x GB is (25 + 10x)

Answer:

Step-by-step explanation:

For Mr Rowley,

Ratio of Number of home works to the number of exit tickets = $\frac{12}{14}$

= $\frac{6}{7}$

= 6:7

For Ms Rivera,

Ratio of Number of home works to the number of exit tickets = $\frac{36}{42}$

= $\frac{6}{7}$

= 6:7

Since, both the ratios are same, fractions will be proportional.

$\frac{12}{14}=\frac{36}{42}$
