Question

A solid wax sphere of radius 5.6 is melted to make conical candles if diameter of base 5.6cm and height 3.2cm . find number of such candle prepared.

Answer 1

ans is there 7 No. of cones

Answer 2

Answer:

7

Step-by-step explanation:

Hi,

Given a solid sphere of radius , R = 5.6 cm

Volume of the sphere = 4/3*π*R³

= 4/3*22/7*(5.6)³ cm³

= 735.618 cm³

Given Radius of the cone , r = 5.6 cm

Height of the cone = 3.2 cm

Volume of the cone = 1/3*π*r²*h

= 1/3*22/7*5.6²*3.2

= 105.088 cm³ . Since the solid wax sphere is made into conical candles,

the number of candles prepared will be

= Volume of Sphere/Volume of Cone

= 735.618/105.088

= 7

Hence, 7 candles are prepared.

Hope, it helps !
