Explanation:
height of cylinder = 4 m
radius of cylinder = 1.5 m
friend, you didn't mentioned that what we how to find in this question but I will try to find out all areas and volumes from given data :
here , curved surface area of cylinder =2πrh
= 2 × 22 /7 × 1.5 × 4
44 × 4 × 1.5 / 7
17 6 × 1.5 /7
264 . 0 / 7
curved surface area of cylinder = 37 . 71 sq . cm
now , total surface area of cylinder = 2πr (r+h)
=2 × 22/7 ×1.5 (1.5+4)
= 44 × 1.5 × 5.5/7
= 363.0/7
= 51.85
total surface area of cylinder = 51.9 sq.cm
volume of cylinder = πr^2h
volume of cylinder = 22 /7 × 1.5 × 1.5× 4
= 198 /7
= 28 . 285 cm^2
volume of cylinder = 28.29 cm^2
