Find the total area of the surface of a solid cylinder whose base radius is 4cm and height is 5cm

A.
56(pi) cm^{2} 
B.
72(pi) cm^{2} 
C.
96(pi) cm^{2} 
D.
192(pi) cm^{2}
Correct Answer: Option B
Explanation
The total surface area of a cylinder = (2pi r (r + h))
= (2 pi (4) (4 + 5))
= (8 pi (9) = 72 pi cm^{2})
