i have a cylinder here i need to find the volume and the surface area

the cylinder is 4cm base height 15cm

would the volume be 3.14 x 42 x 15 = 753.6 i have to give the answer to 3 significant figures so 754cm.

and would the surface area be

2 x 3.14 x 4 x 15 + 2 x 3.14 x 42 = 194.68 i have to give the answer to 2 siginificant figures so 190cm!

is that right?????
