Answer:
150.72
Step-by-step explanation:
To find the surface area, use the provided formula and the values r = 2 and h = 10. The radius of the object is 2 since it is half the distance across the circle which measures 4 inches across through the center.
SA = 2πr² + 2πrh
SA = 2π2² + 2π(2)(10)
SA = 2π*4 + 2π(20)
SA = 8π + 40π
SA = 48π
SA = 48(3.14)
SA = 150.72
