Answer:
87.92 square inches
Step-by-step explanation:
Surface area for cylinder is given by 
where r is the radius and h is the height of cylinder.
Given that candle is cylindrical in shape
Thus, Surface area for candle is calculated as given below\\
Thus, total surface area for candle is 87.92 square inches.
Since they both equal y, set the equations equal to each other: 12x + 39 = 9x, simplify
1) 39 = -3x
2) -13 = x
B. I'm terrible at explaining but I'm sure that's right.
Answer: 1xy+1
Step-by-step explanation:
Hello!
First, let's take a look at the two angles together. We can see that the two angles, when the measures are combined, add up to form a line, DEF. We can therefore see that the two angles DEG and GEF must add up to 180 degrees, as the measure of a line is 180 degrees.
Therefore, we can create our equation.
(7x - 3) + (12x - 7) = 180
Now, solve for x.
7x - 3 + 12x - 7 = 180
19x = 190
x = 10
Finally, substitute x into the angle measures to find the integer measurements.
Angle DEG: 7x - 3
7 * 10 - 3
70 - 3
67 degrees
Angle GEF: 12x - 7
12 * 10 - 7
120 - 7
113 degrees
Just to be sure, add up the angle measurements to make sure they equal 180. 67 + 113 = 180, which means we did our math correctly.
Hope this helps!
