Question

1. In each example given below, radius of base of a cylinder and and its height are
given. Then find the curved surface area and total surface area.
(1) r = 7 cm, h = 10 cm

(2) r = 1.4 cm, h = 2.1 cm

(3) r = 70 cm, h = 1.4 cm

(4) r = 4.2 cm, h = 14 cm​

Answer 1

Answer:

1. CSA=439.6

TSA=747.32

2. CSA=18.4632

TSA=30.772

3. CSA=615.44

TSA=31387.44

4. CSA=369.264

TSA=480.0432

Step-by-step explanation:

tsa of cylinder is 2πr(r+h)

CSA of cylinder is 2πrh
