Answer:
427.04 in²
Step-by-step explanation:
Surface area = 2[tex]\pi[/tex]rh + 2[tex]\pi[/tex]r²
[tex]A = 2\pi (8)(0.5) + 2\pi 8^2[/tex]
[tex]A = 2\pi 4 + 2\pi 64[/tex]
[tex]A = 25.12 + 401.92[/tex]
[tex]A = 427.04[/tex]
So, the surface area of the cylinder is 427.04 in² which is answer choice D.
Answer:
D- 426.04
Step-by-step explanation:
Surface area = 2rh + 2r²
So, the surface area of the cylinder is 427.04 in² which is answer choice D.
