Please help this is (finding the volume of a cone) any tips, answers anything ??
trasher [3.6K]

Answer:

Volume of a cone is v = πr²(h/3), So i think you just substitute the values for every step, 2nd step maybe v = 3.14(2²)(12/3) and then 3.14(4)(12/3) and then 12.56(12/3) then you divide by 3, then simplify from there. The radius =2 and the height is 12. Volume is about 50.24 if you use 3.14 as pi

Step-by-step explanation:

The equation of a cone is v = πr²(h/3), radius is 1/2 of diameter.
