The sum of the volumes of & ltbr & gt cylinder and cone is 883. 125 cubic centimeters.
& ltbr & gt Set cone volume x.
& ltbr & gtX+3x = 883.6438+025。
& ltbr & gtX=220.78 125
& ltbr & gt So the cylinder volume is 662.34375 cubic centimeters and the cone is 220.438+025 cubic centimeters.
& ltbr & gt
& ltbr & gt2. The original volume is 3.14 * 5 * 5 *10 *1/3 = 785/3 cubic centimeters.
& ltbr & gt's current volume is 3.14 * 4 * 9 *1/3 = 452.16/3 cubic centimeters.
& ltbr & gt785/3-452. 16/3 is 332.84/3 cubic centimeters.
& ltbr & gt Therefore, the volume of the new cone is reduced by 332.84/3 cubic centimeters compared with the original volume.
