volume of the cone= 1/3 piR^2h
1570=1/3x3.14xR^2x15
104.7 approx =R^2
R is approx 10.3
1570=1/3x3.14xR^2x15
104.7 approx =R^2
R is approx 10.3

height of cone=15
volume=1570
1/3*pie*r^2*h=1570 (pie=3.14)
1.04*r^2*15=1570
15.6*r^2=1570
r^2=1570/15.6=100 (approx)
r=10
Hope this answer and more queries
