Area of two parallel bases (top and bottom circles of the cylinder:
= 2 (π r²)
Area of rectangle (lateral surface area): height × circumferences
of the base:
= h (2 π r)

Area (Surface) of the right circular cylinder:
= 2 π r² + h(2 π r)

Given:
Height (Diameter) = 2 (8 inches) = 16 inches
π (pi) = 3.14

Solution:
Area = 2π (8 inches)² + 16 inches (2π) (8 inches)
= 2π (64 inches²) + 16 inches (16 π inches)
= 128 π inches²  +  256 π inches²
= 384 inches² (3.14)
= 1,205.76 inches²

ANSWER:  The area is 1,205.76 inches²

Thank you so much. You're a real math wizard, and I'm your fan. I'm sure you're one of those who qualified to the national level of the PMO.
You are smart, too :-) Thanks for nice words.  Rest assured that I also make mistakes because my vision is not that good :-)
You're great. But why don't you consult a doctor ,. Thanks again by the way.
