How do I find the missing value

liberstina [14]

Okay. Since the "y" value and 82* are on the same straight line, their values will always add up to make a sum of 180. So if you subtract 82 from 180 you get 98*. So your "y" value is equal to 98*.

Now, all of the degree values added together should give you a sum of 360, so now we must add the values we know, in order to find the "x" value. So, 112*+82*+98*=292. Now we know that the difference of 360 and 292 will give us the x value. So finally, 360-292=68. So your "x" value is equal to 68.

y=98
x=68

ivanzaharov [21]

<h2>Hello!</h2>

The answer is:

The total area is:

$TotalArea=192.4cm^{2}$

To find the cloasest value to the total surface area that will be painted, we need to calculate the area of a single sphere, and then, multiply it by 5.

We know that the diameter of each sphere is 7 centimeters, so, calculating we have:

Calculating the radius we have,

$diameter=2*radius\\\\radius=\frac{diameter}{2}=\frac{7cm}{2}=3.5cm$
