Question

which barrel shown in the blow figure can hold more water one bareel height 4cm and diameter 3cm and another bareel height is 3cm diameter 4cm​

Answer 1

Answer:

barrel 2

Step-by-step explanation:

barrel is in shape of cylinder

consider "#" to be "pi"

volume of cylinder = #r²h

volume of barrel 1 = #r²h

= ( 22 / 7 ) x ( 1.5 ) ² x 4    [ radius = diameter / 2 = 3 / 2 = 1.5 cm ]

= 3.14 x 2.25 x 4

= 28.26 cm³ ( approx to 2 decimals )

volume of barrel 2 = #r²h

= ( 22 / 7 ) x 2² x 3             [radius = diameter / 2 = 4 / 2 = 2 cm]

= 3.14 x 4 x 3

= 37.68 cm³ ( approx to 2 decimals )

barrel 2 has more volume than barrel 1 so it can hold more water.
