Answer:
60π
Step-by-step explanation:
Formula for surface area of a cylinder is 2πrh + 2r²π
2πrh: this is the formula to find the area of the cylinder itself (circumference of the base times the height of the cylinder)
2r²π: this is the formula to find the area of the 2 circles at the end of the cylinder (area of a circle times 2)
We can substitute h with 7 and r with 3 to solve:
2πrh + 2r²π
2(3)(7)π + 2π(3²)
42π + 18π
60π
That is your answer
