A cone has a diameter of 24 in. and a slant height of 15 in. What is the approximate volume of the cone? Use 3.14 to approximate

g100num [7]

So you are using Volume...

V=1/3(pi)r^2h
as you go thu this equation

15 x 15 =225
12 x12= 144
225-144= 81
81/9=9

which your piece would be 1/3 pi r^2h answer is 1356.48
and you round it to the nearest tenth. So

( 1356.5) is ur answer...... So (B)
