HELP ME!!!!

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

the formula is pie x (r)^2 x (h/3)

Answer 2

can you walk me through.

Answer 4

Can YOU walk me through.

Answer 5

radius will be half the diameter which is 12 in

Answer 6

My brain hurts

Answer 7

OK..... now what?

go here and insert the values..... u will see the formula there

Answer 9

Please. Do you even know how to do it.

Answer 10

V = PIE (3.14) * (square of the radius) * (height divided by 3)

Answer 11

the radius (which is half the diameter) is 12inch
so after adding the values to the formula u get .... 3.14 * 12 * (15/3)

Answer 12

ok hold on

Answer 13

188.4?
