## anonymous one year ago 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

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

can you walk me through.

Can YOU walk me through.

6. SyedMohammed98

radius will be half the diameter which is 12 in

7. anonymous

My brain hurts

8. anonymous

OK..... now what?

9. SyedMohammed98

https://www.google.com/?gws_rd=ssl#q=volume+of+cone go here and insert the values..... u will see the formula there

10. anonymous

Please. Do you even know how to do it.

11. SyedMohammed98

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

12. SyedMohammed98

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

13. anonymous

ok hold on

14. anonymous

188.4?

@SyedMohammed98

16. SyedMohammed98

u u forgot to take the square of the radius (12) which 144 :)

17. anonymous

oh

18. SyedMohammed98

which is 144*

19. anonymous

2260.8?

20. SyedMohammed98
