the volume of a cylinder is 288π cm3.If the radius is 8 cm ,then H=72cm
2πr[h+r]=1280π cm²
2πr[h+r]=1280π cm²

volume of a cylinder = πr²h
πr²h = 288π
r²h = 288
8²*h = 288
h = 288/(8*8)
h = 36/8
h = 9/2
TSA = 2πr(r+h)
= 2π*8(8+(9/2))
=2π*8((16+9)/2)
=π*8(25)
=200π sq.cm
πr²h = 288π
r²h = 288
8²*h = 288
h = 288/(8*8)
h = 36/8
h = 9/2
TSA = 2πr(r+h)
= 2π*8(8+(9/2))
=2π*8((16+9)/2)
=π*8(25)
=200π sq.cm
talli:
V=πr²h
