Answer:

217.699112

Step-by-step explanation:

To find the area let's separate the cube and cylinder into different categories and add them together later.

Cylinder:

SO first we must find the area of the circle and to do so we multiply 2 by 2 and get 4, then multiple by pi, 4 x pi and we get 12.5663706, now we multiply this by 3, 3 x 12.5663706 = 37.6991118. Now that we have the area of the cylinder we can get started on the cube.

Cube:

First we find the area of the base, 9 x 4 = 36. Now we multiply that by 5,

36 x 5 = 180. Now all we do is add them together.

Sum:

180 + 37.6991118 = 217.699112

Answer:

18.84 feet.  let me know if you have ay other questions.

Step-by-step explanation:

The way to find the formula for circumference is kinda complicated so it is best to ust memorize the formula, which is 2πr.  or 2 times pi times the radius.  

Your problem gives you the formula, but instead of 2 and r in it you have d, which is the diameter.

The diameter of the circle is 2 times the radius, so that's why it is replaced.

the radius is the distance from the center fo the circle to one edge, and the diameter is the distance through the circle passing through its center.  so it's the center to one end plus the center to another end.  or r+r which is also 2r.

So d = 2r, so in this problem d =6 feet.

So now the formula πd = 3.14*6 feet = 18.84 feet

I need help on this problem
chubhunter [2.5K]
The value of x
3x°+46°+(2x-1°)=180°(angle sum of △)
5x+45=180°
5x=180°-45
x=135÷5
x=27
x is 27

put x into angle B,we have
2(27)-1
=53

thus angleB is 53°

hope it helps c:

Mr Smith bought x number of shirts for the new members of her chorus. The cost for x number of shirts, including $3.99 shipping
fiasKO [112]

We are given that the cost of each shirt = $12.25

It is given that she bought total 'x' shirts, each of cost $12,25.

So, the cost of 'x' shirts is  dollars

Also, there is a shipping charge of $3.99

So, the total cost of 'x' shirts is

Since, the shirts cost her total $77.49.

We have the equation,

12.25x + 3.99 = 77.49
