60,000 would be the answer because it stays the same if under 5 it stays if above 5 rounds up once
∠1 + ∠3 + 90° = 180°
∠1 + ∠3 = 90°
∠3 = ∠4 (vertically opposite angles)
∠1 + ∠4 = 90°
Therefore, the answer is ∠1 + ∠4
It’s only a vertical angle
I did most of it for you-
Volume of the cone is 13.1
Volume of the cylinder is 18.9
Now, you just subtract two of the flat circular surfaces, because the two shapes are attached, therefore those parts are not surface area. And there is your answer.
Answer:

Step-by-step explanation:
Theoretically, there is not square root of neither 13 nor a negative number so the special symbol is used to represent the square root of a number.
