If water is poured into an inverted hollow cone whose semivertical angle is given by argument of z1. The depth of water increases at a rate equal to the least value of |z2+z3| cm/s. The rate at which the volume of water increases when the depth is 9 cm is mπ cm3/s. Where z1=11+(√2i)2+√27i,z2=8+15i,|z3|=7, (i=√−1). The value of m is |
