1.	97A cylindrical glass tube with radius 10 cm has water upto height of 9 cm. A metal cube of 8 cm edgebe?isimmersed completely. By how much the water level will rise in the glass tu
Answer» H = 9 cm, diameter = 20 cm so, radius = 10 cm and side of the cube = 8 cmTotal volume of the cylinder (after cube is immersed) = Volume of water in cylinder + Volume of water displaced or volume of the cube= 22/710109 + 888= 19800/7 + 512= 2828.57 + 512= 3340.57 cu cmNow, height of water, h1 can be found by equatingπr²h1 with this volume.So,22/71010h1 = 3340.57h1 = (3340.57× 7)/2200h1 = 23383.99/2200Height = 10.63 cmRise in the water level in the cylinder = h1 - h = 10.63 - 9= 1.63 cm not understood

Answer»

H = 9 cm, diameter = 20 cm so, radius = 10 cm and side of the cube = 8 cmTotal volume of the cylinder (after cube is immersed) = Volume of water in cylinder + Volume of water displaced or volume of the cube= 22/7*10*10*9 + 8*8*8= 19800/7 + 512= 2828.57 + 512= 3340.57 cu cmNow, height of water, h1 can be found by equatingπr²h1 with this volume.So,22/7*10*10*h1 = 3340.57h1 = (3340.57× 7)/2200h1 = 23383.99/2200Height = 10.63 cmRise in the water level in the cylinder = h1 - h = 10.63 - 9= 1.63 cm
