The volume of an ice cream cone is 500cm^3. the height of the cone is 16cm. what is the approximate diameter of the base of the cone?

Volume = πr²h/3
Here, V = 500
h = 16

Substitute their values, 
500 = r² * 22/7 * 16/3
500 = r² * 352/21
r² = 500*21 / 353
r² = 10500 / 353
r² = 29.74
r = √29.74
r = 5.45

Now, diameter = 2 * radius = 2 * 5.45 = 10.90 cm

So, Your Final Answer would be 10.90 cm

Hope this helps!

The answer is -pie over 2
