Question

A cone has a diameter of 16 in. and a slant height of 17 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.
1004.8 in3

B.
1138.8 in3

C.
1259.3 in3

D.
4019.2 in3

Answer 1

the volume of a cone is calculated as:
v = pi*r^2*h/3, where r is the radius, h the height.
so lets substitute values:
v = (3.14)(16/2)(17)/3
note we are dividing 16/2 to find the radius from the diameter:
v = 30.8
therefore the volume is 30.8 cubic inches
