Answer:
Step-by-step explanation:
The equation for a cylinder is the radius of the circle times pi squared, multiplied by the height. 3 squared is 9, times pi is 9(pi). If we multiply this by the height, the answer is 90(pi) centimeters in volume.
Answer:
x= 26°
Step-by-step explanation:
it's a 90 degree angle as a whole so just subtract 64° from 90° to get the other angle.
A = (pi) * r^2
A = 3.14 * 11^2
A = 3.14 * 121
A = 379.94 miles
Answer:
It would be a/c
Step-by-step explanation:
Since you're solving for angle F, you have to look at it from the angle F's perspective. Sin is opposite/hypotenuse. I recommended labeling the sides with H, O and A to make it less confusing. The letter opposite angle F is a, so you can label that "O". The side adjacent to angle F is b, so label that side "A" and the side c can be labeled as "H". Since sin is O/H, the correct answer would be a/c.
