The answer to this depends on the angle at which they intersect. If it intersects<span> the cylinder perpendicular to the axis then a circle is formed. </span><span>If the plane intersects the cylinder at an angle, it will form an ellipse. This will be true until the plan is parallel with the axis of the cylinder. At that point, the surface will become a rectangle.</span>
Answer:
for the second questio it is certainly The last choice D
Step-by-step explanation:
2r + 2r + 5 + r + 4r - 3 = 38
9r + 5 - 3 = 38
9r + 2 = 38
9r = 38 - 2
9r = 36
9r/9 = 36/9
r = 4cm
Done!

The mean is 73.44<span>
</span>You could've found this by adding up all the values in the data set, then dividing by how many numbers were in the data set!
66+81+60+72+79+83+60+92+68 = 661
661 ÷ 9 = 73.44
