Question

Circumference of the base of a cylinder is 33 m. If its height is 200 cm, what is its curved surface area?

Answer 1

Answer:

Step-by-step explanation:

Circumference of circle is 2πr

33 = 2 x 22/7 x r

33 x 7/ 22 x 2 = r

r = 5.25 m

H = 200 cm = 2m

C.S.A. of cylinder is 2πrh

C.S.A. = 2 x 22/7 x 5.25 x 2

C.S.A. =  66 m

Answer 2

Answer:

6600 metres is the curved surface area of the cylinder

Step-by-step explanation:

Circumference of the base of a circle = 2πr = 33 metres

2 × 22/7 × r  = 33 metres

44/7 × r = 33 metres

33 × 7/44 =r

Radius = 5.25 metres

Curved surface area of a cylinder = 2πrh

Radius = 5.25 metres

Height = 200 centimetres

C.s.a = 2 × 22/7 × 5.25 ×200

C. s. a = 44/7 × 1050

C.s.a = 6600 metres

Curved surface area of the cylinder is 6600 m
