Question

the volume of a cone is 1570 cubic cm. If the diameter of the base is 20cm. Find the height of the cone​

Answer 1

Answer:

$Volume \: of \: cone=1570cm³</p><p> \\ \frac{1}{3} πr²h=1570 \\ </p><p> \frac{1}{3} × \frac{22}{7} × \frac{20}{2} × \frac{20}{2} ×h=1570 \\ </p><p>h=1570×3× \frac{7}{22} × \frac{2}{20} × \frac{2}{20} \\ </p><p>h= \frac{157×3}{22×10} </p><p> \\ h= \frac{471}{220} \\ </p><p>h=2.14cm \\ </p><p>Therefore, \: the \: height \: of \: the \: cone \: is \: 2.14cm$
