Answer:

954.56 cm²

Step-by-step explanation:

Firstly i would calculate the circumference of the circles on top of the cylinders:

Circumference of circles = \pi d or 2\pi r

d = diameter

r = radius

I will use 2\pi r

circumference = 2 x 3.14 x 8 = 50.24 cm

⇒ This would help me to find out the surface area of the side of the cylinder

50.24 x 11 = 552.64 cm²

⇒ This is the surface are of the sides

Now we have to find the are of the two circles on the top and the bottom:

Area of a circle = \pi d^{2}

d = diameter

3.14 x 8² = 200.96

⇒ There are two circles so you would times 200.96 by 2

200.96 x 2 = 401.92

Add all the values up:

401.92 + 552.64 = 954.56 cm²

I hope this helps!

Ramiro earns $20 per hour during the week and $30 per hour for overtime on the weekends. One week Ramiro earned a total of $650.
nika2105 [10]

Answer:

Week=25 Hours

Weekend= 5 Hours

Step-by-step explanation:

So we need to use the info they gave us and create two equations. Firstly we know how much he gets paid per hour during the week (x) and how much he gets paid on the weekend (y).

$20x+$30y=$650

We get this because we know the combined rates he is paid times the hours should add up to the amount he earned.

The next equation will be made off of the information that he worked 5 times as many hours during the week as on the weekend. This tells us that we will take the weekend hours (y) and multiply them by 5 in order to get the week hours (x).

x=5y      Now, since we have one variable by itself, we can plug it in for x in the first equation.

20(5y)+30y=650    Our first step here is to distribute the 20 to the 5y in order to eliminate the parenthesis.

100y+30y=650    Next add the like terms together (100y+30y).

Now all we have to do to find y is divide by 130 on both sides to get y alone.

130y=650  

________

130     130

y=5             Now to solve for x we just plug our y value into one of the equations above. I'm going to use the second equation.

x=5(5)

x=25

How do you graph y=7/2x-2
RoseWind [281]
You can either make a table using any numbers you would like (I would suggest -5 to 5) and then graphing the rule

ex. (7/2)(-5)-2 = -19.5 (I multiplied (7/2) by -5 and then subtracted 2) 


Or you can put the rule in a graphing calculator and check the points from there

Calculate the max shear of cantilever balcony 2m wide 0.2m deep and 1.5m length.
Vikki [24]

Answer:

14.4 kN

Step-by-step explanation:

cantilever balcony 2m wide 0.2m deep and 1.5m length.

= 2 x 0.2 x 1.5

= 0.6 m³

weight of the balcony

= 0.6 x 24

= 14.4 kN.

therefore the max shear 14.4 kN and is acting at support.
