What is the volume of a sphere if the radius is 6.3?
Use 3.14 for pi.
Round your answer the the nearest two decimal places.

The answer to your question is V = 1046.60 u³

Step-by-step explanation:

Data

Volume = ?

radius = 6.3

π = 3.14

Formula

V = (4/3) πr³

Substitution

V = (4/3) (3.14)(6.3)³

Simplification

V = (1.333)(3.14)(250.047)

V = 1046.6017 u³

- Rounding to two decimal places just consider the six and zero

V = 1046.60 u³

Let's multiply the first equation by 3. (As you can see y's coefficient in the first one is 1 and in the second one is -3 , we will multiply the first equation by 3 so when we add the equations their sum will be 0)



Now let's add this new equation and our second equation.



We found x=-3

Now let's plug x's value in one of the equations to find y's value.



So we found y=5

Solution ;

(-3, 5)
