The midpoint of AB is M(2,-2). If the coordinates of A are (8, 1), what are the

coordinates of B?

I need answers

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

i believe the answer is the polygon, heptagon.

47 - 90 = 43

43 - 180 = x

x = 137

answer: i wpould go with c
