volume of cylinder V=\(π*(r)^2*h\)
quant A: p=10
new radius=0.9r
new height=1.1h
new volume =\((0.9)^2 *1.1*V\)=0.891V
quant B: p=20
new radius=0.8r
new height=1.2h
new volume =\((0.8)^2 *1.2*V\)=0.768V
so quant A>quant B
option A is correct
quant A: p=10
new radius=0.9r
new height=1.1h
new volume =\((0.9)^2 *1.1*V\)=0.891V
quant B: p=20
new radius=0.8r
new height=1.2h
new volume =\((0.8)^2 *1.2*V\)=0.768V
so quant A>quant B
option A is correct
