Answer:
SA= 829.38 Inches² which is 829.38/3.14159 = 264π inch³
V = 110.43 inches³. which is 110.43/ 3.14159 = 35.15π inch³
Step-by-step explanation:
To find the surface area of cylinder, we calculate two area of circle 2πr² and one area of rectangle 2πrh first, and then add them 2πr²+2πrh.
SA of a cylinder =2πrh+2πr², where π≈3.14159
Radius given is 12/2 = 6 inches
= 2 x π x 6 x 16 + 16 x π6 x 6 ≈ 829.3804 = 829.38 Inches²
Volume = h*π *r^2
V = 16 x π
= 110.43 inches³.
