Answer:
r - 1.69 inches
Step-by-step explanation:
Volume of a cone is
V = πr^2h/3
V - volume of the cone
π - 3.142
h - height of the cone
r - radius of the cone
We are provided with the values of
V - 12
π - 3.142
h - 4
r - ?
Insert the above values into the formula
V = πr^2h/3
12 = 3.142 * r^2 * 4/3
12= 3.142 * 1.33 * r^2
12= 4.189r^2
Divide both sides by 4.189
12 / 4.189 = 4.189r^2/ 4.189
2.865 = r^2
r = square root of 2.865
r = 1.6925 inches
r = 1.69 inches
