For the following exercises, find the surface area of each right cylinder.

r = 9 cm , h = 15 cm

Sagot :

Answer: the answer is (1357.17)cm² approx

Step-by-step explanation: we know that  

surface area = 2π(r+h)

where r = radius and h = height of cylinder

given r = 9cm , h = 15cm

so, surface area = 2π × 9 × ( 9+15)

                             =2π×216

                              =1357.17 approx
