ANSWER THESE MATH QUESTIONS AND GET A MEDAL!!!!!!!
The volume of a cone is three hundred cubic kilometers. If the radius of the base is 5 kilometers, what is the height of the cone? Use three point one four for pi. Show your work and round to the nearest tenth.
please write answer in words like "i did this then i did that"
do u know the formula for the volume of cone???
Hello sweety! V=πr^2h/3 is the formula for cone. so, if the volume is 300, 300=πr^2h/3 would be it. than the radius is 5. so that would make 300=π5^2h/3 so if you work it out, the answer would be 11.46
I will work out the steps.
ok thanks
300=3.14(5^2)h/3 300 = 3.14(25)h/3 300 = 78.5h/3 now multiply 3 to both sides to cancel out fraction. 900 = 78.5h finally, you divide 78.5 on each side to get the h (height) alone. h= 11.46496815...... would be the height! so if you round to hundreds it will be 11.46 as your final answer !!! If you have trouble following, I will Draw and work it out for you! Let me know.
Thank you for the medal @MaimiGirl I will return you for trying!
ur welcome thanks for the medal u're very nice :)
