Let the radius of the base of the cone be r cm.
h = 15 cm, Volume = 1570 cm3
{tex}{1\over3}\pi r^2h{/tex}= 1570
{tex}1\over3{/tex} × 3.14 × r2 × 15 = 1570
{tex}r^2={{1570\times3}\over3.14\times15}{/tex}{tex}r^2=100{/tex}
{tex}r=\sqrt{100}{/tex} ⇒ r = 10 cm.
∴ the radius of the base of the cone is 10 cm.
