Question

the circumference of the base of the cylinder is176cm and its hight is 65cm. find its total surface of the cylinder​

Answer 1

Answer:

circumference of a circle=2πr

2×22/7×r=176

r=28cm

Tsa of a circle=2πr(h+r)

T.s.a=2×22/7×28(65+28)

T.s.a=16368

Answer 2

Step-by-step explanation:

GIVEN:-

CIRCUMFERENCE OF BASE OF CYLINDER = 176cm

HEIGHT = 65cm

TO FIND:-

THE TOTAL SURFACE AREA OF THE CYLINDER

STEPS:-

2πr = 176cm

2 × 22/7 × r = 176

R = 176 × 7 ÷ 44

R = 28cm

TOTAL SURFACE AREA OF CYLINDER =2πr(R+H)

2 ×22/ 7 ×28 (28 + 65)

44 × 4 × 93

= 16368

HENCE TSA OF CYLINDER = 16368cm
