The answer is 5a pretty sure
A=2πrh+2πr2=2·π·6·25+2·π·6^2 so the answer is D
Tigers! Have a great day!
Answer:
We can find if a critical point is a local minimum or maximum by looking at the second derivatives.
Step-by-step explanation:
If you take the first derivative, you will find the slope at the given point, which if it is a minimum or a maximum will be 0.
Then we take the second derivative. If that number is a positive number, then we have a local minimum. If it is a negative number, then it is a local maximum.
x = 15°
The angle of a straight line is 180°.
37 + 9x + 8 = 180
9x + 45 = 180
9x = 135
x = 15°
