Answer:
surface area of cylinder= 2×pi×r (h+r)
surface area of cylinder=2×22/7×7(7+4)
surface area of thecylinder =2×22/7×7×11
surface area of thecylinder =484 mi²
276.460 (this has been rounded to the nearest thousandths
Step-by-step explanation:
Surface area of a right cylinder is A= 2πrh+2πr^2.
π being 3.14.
A= (2)(3.14)(4)(7)+(2)(3.14)(4)^2
