Observe the following statements I) If the radius of spherical ball is increased by $\dfrac{1}{2}\%$ then approximate increase in volume is $1\%$ II) In measuring the radius and height of a cone as $5\ cm, 10\ cm$ there are errors $0.02\ cm, 0.01\ cm$ respectively. Then error in volume approximately is $2.25\pi c.c$

  1. only $I$
