B

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( , )

Here (x₁, y₁ ) = A(2, - 1) and (x₂, y₂ ) = B(- 3, 1) , then

midpoint = ( , ) = ( , ) = ( - , 0 ) → B

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
