Answer:
54π cm²
Step-by-step explanation:
It's pi, or π, but definitely not "pie."
The surface area has two parts: the vertical side and the two ends.
The formula for the area of the vertical sides is A = πr²h, where r is the radius and h is the height. Here, we have:
A = π(3 cm)²(5 cm) = 45π cm²
Each of the ends has the following area: A = πr², or A = 9π cm²
Thus, the total surface area of the cylinder is 45π cm² + 9π cm², or 54π cm²

1/8 is the answer i took the k12 test
Hey there!
Let's combine like terms!
First, let's write them together, like so:
-2.8d+2.8d-2.8d+2.8d-1.33+3.4-1.33
And now we can see that -2.8d and 2.8d cancel out:
-2.8d+2.8d-1.33+3.4-1.33
And they cancel out again:
-1.3+3.4-1.33
Now all we have to do is add the numbers together:
0.77
Hope it helps!


When a transversal crosses a pair of parallel lines same side interior angle pair are supplimentary.
What is angle?
Angle is the space between two intersecting lines or surface at or close to the point where they meet.
Sol-We are given that two parallel lines are intersected by a transversal.
We have to find pair of supplementary angles.
Supplementary angle: Two angles whose sum is equal to 180 degrees are called supplementary angles.
Corresponding angles.
It is not necessary that sum of corresponding angles is always equal to 180 degrees.Therefore, pair of angles are not always supplementary.
Thus it is true.
