Surface Area formula of a cylinder:
S.A = 2 × Area of base + Perimeter of base × Height of prism
= 2[tex] \pi [/tex]r² + 2[tex] \pi [/tex]rh
= 2[tex] \pi [/tex](10)² + 2[tex] \pi [/tex](10)(100)
{We took 10 ft as the radius because the diameter is 20 ft, so the radius is half the diameter}
= 200[tex] \pi [/tex] + 2000[tex] \pi [/tex]
= 2200[tex] \pi [/tex] ft² (in terms of [tex] \pi [/tex])
= 6911.5 ft² (to the nearest tenth)
