Question

the circumference of a cylinder is 52.8m and its height is 6cm Find the volume​

Answer 1

Step-by-step explanation:

circumference of cylinder =2πr

first find radius

circu. of cylinder=2πr

52•8=2πr

(52•8)÷2π= r

then volume of cylinder =πr²h. {r = (52•8)÷2π}

{ h=6cm}

volume of cylinder = π×(52•8)²×6÷(2π)²

=(2787•84×6)÷4π

=16727•04÷4π

first divide whole by 4 then answer divide π=3•14

16727•04÷4= 4181•76

then answer divide π=3•14

4181•76÷3•14=1331•77

VOLUME OF CYLINDER =1331•77m³
