Based on the calculations, the surface area (SA) of a cylinder is equal to: B. 2,813.44 in.²
<h3>How to calculate surface area of a cylinder?</h3>
Mathematically, the surface area (SA) of a cylinder can be calculated by using this formula:
SA = 2πrh + 2πr²
<u>Where:</u>
The dimensions of this new cylinder would be equal to:
Radius = 8 × 2 = 16 in.
Height = 6 × 2 = 12 in.
Substituting the given parameters into the formula, we have;
SA = (2 × 3.14 × 16 × 12) + 2 × 3.14 × 16²
SA = 1,205.76 + 1,607.68
SA = 2,813.44 square inches.

Answer:
-2x-5
Step-by-step explanation:
By distributing the -2 to the x+10 we get, "-2x-5". This is our final simplified answer.
The team ran 2 miles.
Step-by-step explanation:
Step 1; The track is 
miles long and the team ran 2
laps on it. To calculate the distance run we multiply the number of laps ran with the distance on each lap.
Distance run = Number of laps × Distance on each lap.
Step 2; We convert 2 from a mixed fraction into an improper fraction. To do this, we multiply the whole number with the denominator of the fraction and add with it the numerator of the same fraction whereas the denominator remains unchanged. To convert the fraction 2 = ((2 × 3) + 2) / 3 = 
.
Distance run = Number of laps × Distance on each lap = × = 
= 2 miles.
