Answer:
answer d is the right answer
7 = r^1/2 is the same as saying 7 = square root of r. So, to get rid of the square root sign on the r, you need to square it, and when you do something to one side of the equation, you have to do the same to the other side. So after squaring both sides, you get 49 = r.
Answer:
Area of A = 32ft
Area of B = 36ft
Step-by-step explanation:
All you need to do to solve is multiply width * length * height.
If you do so,
Area of A = 3 * 2 * 5 1/3
= 6 * 16/3
= 32
Area of B = 6 * 4 * 1 1/2
= 24 * 3/2
= 36
