Answer:

A: (t + p, r)

Step-by-step explanation:

To find the midpoint of EC

Let (x1, y1) = E(2t, 0) and (x2, y2) = C(2p, 2r)

Midpoint = [(2t + 2p)/2 , (0 + 2r)/2]

= (2(t + p)/2 , 2r/2)

= (t + p, r)

2. Simplify to 3.14(20.25)(6)

3. Simply multiply all three numbers using a calculator, or one by one if that's the preferred option.
