The heights of 10 girls were measured in cm and the results are as follows. 135, 150, 139, 128, 151, 132, 146, 149, 143, 141. i) What is the height of the tallest girl? ii) What is the range of the data?

Observe the following statements I) If the radius of spherical ball is increased by 1/2% then approximate increase in volume is 1% II) In measuring the radius and height of a cone as 5cm,10cm there are errors 0.02 cm, 0.01cm ewspectively. Then error in volume approximately is 2.25pic.c Correct statement is
