Question

Guys, please help me please

Answer 1

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
