Answer:

Total Surface Area of Cylinder = 3,692.64 sq cm

Volume of Cylinder = 9,702 cubic cm

Step-by-step explanation:

Given ;

Base of a cylinder = 21 cm

Height of a cylinder = 7 cm

TSA of a Cylinder = 2πr ( h + r )

TSA = 2 × 22 / 7 × 21 ( 21 + 7 )

TSA = 44 / 7 × 21 ( 28 )

TSA = 6.28 × 588

TSA = 3692.64 sq cm

Volume of Cylinder = πr2h

Volume ( V ) = 22 / 7 × 21 × 21 × 7

Volume = 22 × 21 ×21

Volume of Cylinder = 9,702 cubic cm
