Calculate the surface area of each solid with explanation ​

Mathematics
1 answer:
juin [17]3 years ago
6 0

Answer:

602.88

Step-by-step explanation:

The two lids

Area = pi * r^2

d = 12

r = d/2

r = 12/2

r = 6 cm

Area = 3.14 * 6^2

Area = 3.14 * 36

Area =  113.04

Both Lids =                                           226.08

Cylinder Body

Circumference =  2*pi*r*h

Circumference = 2*3.14 *6 * 10         <u>   376.8</u>

Total Area =                                         602.88

In parallelogram LMNO, what are the values of x and y?
Norma-Jean [14]
In a parallelogram, if two opposites are congruent, then the two opposites are equal. We apply this description to solve the problem.
∠O = ∠M since they are opposite
2x = 3x - 55
55 = 3x - 2x
55 = x

Total of all angles in the parallelogram is 360°
∠L + ∠N +∠O +∠M=360°
360° - ∠O -∠M = ∠L + ∠N note that ∠L =∠N
360° -110° -110° = 2∠N
70° = ∠N

Solving for Y,
∠N = 5Y = 70°
Y=70/5
Y=14

Therefore, the value of "x" is 55 and the value of "y" is 14. The answer is the letter "C".

Will give brainliest for correct answer.
Naddika [18.5K]
The answer to this problem is all real numbers except for 4. When looking at this function, one can see that most numbers are possible. But, the only number that won't be possible is four. That's because the fraction \frac{1}{x-2} will always equal something greater than or less than zero. Since it's never going to equal zero, and since there is already a 4, that means that the range of this function is all real numbers except for 4.
