.. A cylindrical candle has base radius 3.5 cm. How high it must be made to holdw high it must be made to hold 308 cm of wax

Answer»

Volume of cylinder with radius r and height h is given by

V = πr²h

It is given that,a cylindrical candle has base radius 3.5

The volume of cylindrical candle = 308 cm cube

To find the height of candle

Volume of candle is given by

V = πr²h

308 = 3.14 x 3.5 x 3.5 x h

h = 8cm

Therefore the height of cylindrical candle= 8 cm
