Question

Find the surface area of this right circular cylinder. The radius is 3 meters and the length is 6 meters. Answers;; 18? m3 45? m3 9? m3 54? m2

Answer 1

$2 \times (\pi \times {3}^{2} ) + 6 \times (2\pi \times 3) \\ = 18\pi + 36\pi \\ = 54\pi \: ( {m}^{2} )$
that is (2 of area of circle + area of square)
