Find the surface area of a cylinder
2 answers:
A = 2•3.14•3•8 + 2•3.14•3^2 = 207.34512
Answer:
Surface area = 207.24 in²
Step-by-step explanation:
Remember to always convert the diameter into a radius.
D = 6 in (divide it by two to get the radius) R = 3 in
Radius = 3 in
Formula:
SA = 2rh + 2r²
Solution:
SA = 2rh + 2r²
SA = 2(3.14)(3)(8) + 2(3.14)(3)
SA = 2(3.14)(3)(8) + 2(3.14)(9)
SA = 150.72 + 56.52
SA = 207.24 in²
