Explanation:
#"the volume (V) of a cone is calculated using "#
#•color(white)(x)V=1/3pir^2h#
#"where r is the radius of the base and h the height"#
#"we require to find r the radius"#
#"using the formula for the circumference (C) of a circle"#
#•color(white)(x)C=2pir#
#rArr2xx3.14xxr=56.52#
#rArr6.28r=56.52#
#"divide both sides by "6.28#
#(cancel(6.28) r)/cancel(6.28)=56.52/6.28rArrr=9#
#rArrV=(3.14xx81xx5)/3~~423.9toD#
