The base of the cylinder is a circle of radius r.
The volume formula is V+=+pi%2Ar%5E2%2Ah
given: d=10cm and height is 13cm
since d=2r.=>.......r=5cm
V+=+pi%2A%285cm%29%5E2%2A13cm
V+=+pi%2A25cm%5E2%2A13cm
V+=325%2Api%2Acm%5E3

The formula for surface area of a cylinder is
S%5Barea%5D++++++++++=2%2Api%2Ar%5E2+%2B+2%2Api%2Ar%2Ah
S%5Barea%5D++++++++++=2%2Api%2A%285cm%29%5E2+%2B+2%2Api%2A%285cm%29%2A13cm

S%5Barea%5D++++++++++=2%2Api%2A25cm%5E2%2B+130pi%2Acm%5E2
S%5Barea%5D++++++++++=%2850%2B130%29pi%2Acm%5E2
S%5Barea%5D++++++++++=180%2Api%2Acm%5E2
