Answer:
Volume= πr^2h= 128π
r^2h= 128
4^2*h=128
16h= 128
h= 8 cm
CSA= 2πrh
=2*π*4*8
=64π

Answer:
volume of a cylinder pi r2h=128pi=pi×4×4×h= 128pi= 4×4×h=128=16×h=128 h=128/16= 8 ans find the c.s.a = 2pi rh =2×22/7×4×8=1408/7=0.0049 ans solved
Step-by-step explanation:
volume of a cylinder =128pi , radius =4cm
