Given formula: SA = 2πr2+2πrh
Given information:
r = 4
h = 8
π = 3.14
Substitute the values into the formula:
SA = 2(3.14)(4)^2 + 2(3.14)(4)(8)
SA = 2(3.14)(16) + 2(3.14)(32)
SA = 100.48 + 201.06
SA = 301.54
Therefore, the surface area of the cylinder is approximately 301.5 square units.
Find the surface area of the cylinder. Use the formula SA = 2πr2+2πrh
. Use 3.14 for π
. Round your answer to the nearest tenth.
