Answer:

Step-by-step explanation:
Let, A=(3,2)
B=(-1,10)
So, The equation will be

So, we need to find { curved surface area[pi*d*h] + top area[pi*(d^2)/4] }
just
substitute.
Step-by-step explanation:
the angle ABC = 180 - x, as ABD and ABC are complementary angles on top of the bottom line : all angles around a point on one side of a line are always adding up to 180 degrees.
but because we also know that the sum of all angles in a triangle is 180 degrees too, we can say
180 = ACB + ABC + CAB
180 = y + 180 - x + CAB
0 = y - x + CAB
x = y + CAB
x - y = CAB
therefore, the second answer option is correct.
