Question

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 the value of straight pi. Round your answer to the nearest tenth, if necessary. (Hint: V equals 1 third straight pi r squared h ) A. 1248.6 in3 B. 1356.5 in3 C. 2260.8 in3 D. 5425.9 in3

Answer 1

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)
