Question
A cylindrical bucket of radius 42 cm and height 48 cm is
full of water. The water is emptied into a rectangular rub of length x cm and breath 84 cm. If the height in the tub rises by 24 cm, then what is the value of x? (Take π =22/7)?Solution
volume of water in cylindrical bucket = volume of water in rectangular tank πr² h= lbh (22/7) x 42 x 42 x 48 = 'x' x 84 x 24 (266112/2,016) = x x = 132
