Add all the angles displayed and add 90 degrees because we can see one of the angles is a right angle, Now take the total and subtract 540 with the sum and you will get 114 which is your answer.
Answer:
½pi or 0.5pi units²
Step-by-step explanation:
Area : angle
9pi : 2pi
x : pi/9
9pi/2pi = x/(pi/9)
4.5 × pi/9 = x
x = ½pi or 0.5pi units²
The formula for the surface area of a cylinder is:
Plug in what we know, use 3.14 to approximate for pi(radius is half the diameter, 30/2 = 15):
Simplify:
Subtract 1413 to both sides:
Divide 94.2 to both sides:
So the height is approximately 45 millimeters.
