The surface area of the cylindrical ring is given by
πdh
where d is the diameter and h is the height:
π•6.3•48 = 950.02
The answer is C. 950.02 in^2

Answer: Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Diameter of cylinder = 6.3 inches

Radius of cylinder is given by

\frac{6.3}{2}\ in

Height of cylinder = 48 in.

As we know the "Surface area of cylinder":

Area=2\pi rh\\\\Area=2\times \frac{22}{7}\times \frac{6.3}{2}\times 48\\\\Area=950.02\ in^2

Hence, Option 'C' is correct.

Of means multiplication. So the question is 1/3 X 1 1/2. First make 1 1/2 improper: 3/2. Then multiply the numerators (top numbers) and denominaters (bottom numbers): 1x3=3, 3x2=6, =3/6. Now simplify 3/6=1/2. Then multiply that by 2, since he used 2 pieces: 1/2x2=1. John used 1 meter :)
