Answer:

4 cm radius

- Volume = 267

- Surface area = 201

___

Square root 3

- Volume = 22

- Surface area = 38

Step-by-step explanation:

4/3 * 3.14 * r^3 is formula. For this, I am going to use 3.14 for pi.

Since r = 4, r ^3 = 64.

Now we do 64 * 3.14 * 4/3 = ~ 267.

Now let's do the surface area.

4 * 3.14 * r^2 is the formula. For this, I am going to use 3.14 for pi.

Since r = 4, r ^ 2 = 16.

4 * 16 * 3.14 = ~ 201

______

Now, let's do Square root of three.

3 square root of 3(i cubed it) * 4/3 * 3.14  = ~ 22

For surface area it is 3 * 4 * 3.14 = ~ 38.
