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

Total surface area (includes lateral and both ends)
=2πr(r+h)
=2π(4.5+5)
=19π cm²
Volume = πr²h cm³
Capacity = πr²h ml 
could somebody help me and write this out from ac i need the answers so i can pass my math course
