A solid spherical ball of iron with radius 6 cm is melted and recase tin to three solid spherical balls . The radii of the two of the balls are 3 cm and 4 cm respectively determine the diameter of the third ball.
Least count of a vernier callipers is 0.01 cm When the two jaws of the instrument touch each other the 5th division of the vernier scale coincide with a main scale division and the zero of the vernier scale lies to the left of the zero of the main scale. Furthermore while measuring the diameter of a sphere, the zero markof the vernier scale lies between 2.4 cm and 2.5 cm and the 6th vernier division coincides with a main scale division. Calculate the diameter of the sphere.
A spherical ball of radius 3 cm is melted and recast into three spherical balls. The radii of the two of the balls are 1.5 cm and 2 cm respectively. Determine the diameter of the third ball.
The diameters of three solid balls of iron are 6 cm, 8 cm and 10 cm. They are melted and recast a solid ball. Find the diameter of this ball.
A spherical ball of lead 3cm in diameter is melted and recast into three spherical balls.If the diameters of two balls be (3)/(2)cm and 2cm, If find the diameter of the third ball.
A screw gauge has main scale divisions of 1 mm each and its circular scale has 50 division. While measuring the diameter of a ball, cap end is after 19^("th") marking of main scale and 21^("st") division of circular scale coincides with the reference line. What is the measured diameter diameter of the ball?
