Question

the circumference of the base of a cylinder is 176 cm the height of cylinder is 65 cm .find the volume of cylinder and it's total surface area

Answer 1

Hiii friend,

Circumference of base of cylinder = 176


2πR = 176

2 × 22/7 × R = 176

R = 176×7/44 => 28 cm


Height of cylinder = 65 cm



Therefore,


Volume of cylinder = πR²H => 22/7 × 28 × 28 × 65

=> 22 × 4 × 28× 65


=> 160160 cm².



TSA of cylinder = 2πR(R+H)


=> 2 × 22/7 × 28 ( 28 + 65)


=> 44 × 4 × 93


=> 16368 cm².




HOPE IT WILL HELP YOU....... :-)

Answer 2

Hey!

_____________________________________________________________________________________________

Given :-

Circumference of base of cylinder = 176cm

Height of cylinder = 65cm

_______________________________

Solution :-

=> 2πr = 176cm

=> 2 × 22/7 × r = 176

=> R = 176 × 7 ÷ 44

=> R = 28 cm

_______________________________

•Volume of Cylinder :-

= πr²h

= 22/7 × 28 × 28 × 65

= 22 × 4 × 28 × 65

= 160160

_______________________________

•TSA of cylinder :-

= 2πr(R + H)

= 2 × 22/7 × 28 (28 + 65)

= 44 × 4 × 93

= 16368
