Step-by-step explanation:
The height of cylinder = Diameter of cylinder
18 cm = 2×radius of cylinder
9 cm = radius of cylinder
Volume of cylinder = 2πr^2 h
=2×22/7×9×9×18 cm^3
=32076/7 cm^3
=4582.28 cm^3

Answer:
Diameter and height is equal so,
Height=18 = diameter
(a) diameter = r/2
= 18/2
= 9 cm
radius of cylinder is 9 cm
(b) volume of cylinder is = πr²h
= 22/7 × 9 × 9 × 18
= 22/7 × 81 × 18
= 22/7 × 1458
= 22 + 208
= 230
