Question

Find the surface area of a cylinder with a base radius of 2 m and a height of 3 m, write the answer in terms of pie

Answer 1

The answer is: 20
`\pi` m² .
__________________________________________________________
Step-by-step explanation:
__________________________________________________________
Formula for "S.A." (Surface area) of a cylinder

S.A.
= 2
`\pi` r² + 2
`\pi` * r * h ;
_______________________________________
in which "r" = length of radius of circle at the end; and "h" = "height" ;
__________________________________________
Given: r = 2 m ; and h = 3 m ;
__________________________________________
We can "plug in" these given values; and solve for the "surface area" in terms of
"
`\pi`" .
____________________________________________
S.A. = 2
`\pi` r² + 2
`\pi` * r * h ;

= 2
`\pi` * (2)² + 2
`\pi` * (2) * (3) ;

= 2
`\pi` * (4) + 2
`\pi` * (6) ;

= (8
`\pi`) + (12)
`\pi`

= 20
`\pi` m² .
