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. |
