Question

Please help, round to the nearest thousandth

Answer 1

276.460 (this has been rounded to the nearest thousandths

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

Answer 2

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
