Answer: A≈1015.4
Step-by-step explanation:
A=2πrh+2πr2=2·π·8·12.2+2·π·82≈1015.36275
Answer:
407 mm²
Step-by-step explanation:
The formula for the surface area of a clyinder is: A = 2[tex]\pi[/tex]r · (r + h)
Plugging in the given values, we have: A = 2[tex]\pi[/tex]4 · (4 + 12.2)
A = 2[tex]\pi[/tex]4 · (4 + 12.2)
A = 2[tex]\pi[/tex]4 · 16.2
A = 2(3.14)4 · 16.2
A = 406.944
A = 407 (rounded)
hope this helps!
