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
olga55 [171]
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!

frosja888 [35]

Answer:

4

Step-by-step explanation:

We have been given that it equals 19 when added to 3 and multiplied by 4 so follow these steps:

1. set the equation 4x+3=19

2. solve for x

4x+3-3=19-3

This is used to solve for x

3. 4x=16 is found

4. if 4x=16, we divide 16/4 and get 4!

That's your answer hope it helped!
