Answer:
The surface area of this cylinder. is <em><u>266π cm²</u></em>
Step-by-step explanation:
Surface Area of Cylinder (SA) = 2πrh+2πr²
since r = 7cm & h = 12 cm
Then SA = 2 π (7)(12) + 2π(7²)
SA = 168π + 98π
∴ SA = 266π cm²
226pi
2 * pi * 7 *(7+12)
The third option
This is because you multiply the variable cost (9), by the amount they make, which is x.
The correct answer is below:
9 units
the y value doesnt change, so the distance from -5 to 4 is 9 units
