A cylindrical tin can has a radius of 4.5cm and a height of 5 cm

(a)What is the surface area of the can

(b)What is its volume?

(c)What is the cans capacity

could somebody please answer this question so i can get past with math

    a. 2pir^2 +2pirh
    = 2pi(4.5^2)+ 2pi(4.5)(5)
    = 127.23+141.37
    = 268.6cm^2
    b. pir^2h
    = pi(4.5^2)(5)
    = 318.09cm^3
    c. the capacity and volume are the same thing: 318.09 cubic cm
