There are 16 possible outcomes.

Step-by-step explanation:

For this question, we combine the possibilities together.

R = red G = green O = orange B = blue

There are 16 possible outcomes.

You can also find the total number of possible outcomes by using the formula for permutations. n is the total number of choices. r is the number you are examining.

$\frac{n!}{(n-r)!}$

$\frac{4!}{(4-2)!} =12$

This number doesn't include the outcome of having the same color twice. There are four colors meaning that their four outcomes in which the same color is spun twice.

12 + 4 = 16

A sphere has a volume of 288 Pi in^3. Find the surface area of the sphere

lorasvet [3.4K]

Answer:

Step-by-step explanation:

The formula for determining the volume of a sphere is expressed as

Volume = (4/3) × πr³

The volume of the given sphere is expressed as 288π inches³. It means that

(4/3) × πr³ = 288π

4r³/3 = 288

4r³ = 3 × 288 = 864

r³ = 864/4 = 216

Taking cube root of both sides, it becomes

r = 6

The formula for determining the surface area of a sphere is expressed as

Area = 4πr²

π = 3.14

Therefore,

Surface area = 4 × 3.14 × 6² = 452.16 inches²
