Answer:
Height of cylinder=28 cm
volume of cylinder = πr square h
H=28
R=30
put the value in above formula
= π 30 cm square × 28 cm
=900cm square × 28 cm
π =22/7
volume=22/7×900×28
=22 4 cm ×900cm square
=88 cm ×900cm square
we get
volume= 79200 cm ^3

Step-by-step explanation:
height of cylinder (H) = 28cm
radius of cylinder (r) = 30cm
volume of cylinder = πr^2h
= 22/7 × (30)^2× 28
= 22×900×4
= 79200cm^3
