Answer:

(125/6)π units³

Step-by-step explanation:

The formula for the surface area of a sphere is A = 4πr².  Solving this for r² yields:

                     A

            r² = ------

                     4π

and in this case r² is:

                    25π

            r² = ---------, or 25/4 units²

                     4π

Thus, the radius, r, is 5/2 units.

The volume of a sphere of radius r is V = (4/3)πr³ units³

Here, that volume is V = (4/3)π(5/2)³ units³

                                         4π     125 units³

                                   =   ------ · ------------------ = (125/6)π units³

                                           3            8

How do I do the bus stop method?
hichkok12 [17]
The bus stop method is just like division.
Ex
137÷5= 
1.) 5 goes into one zero times so there is a zero on top.
2.) 5 goes into 13 two times, so after the zero there is a 2.
3.) 5 goes into 37 seven times so there is a 7 after the 2.
4.) There is a 2 left and five can't go into school therefore that is a remainder.

Answer for s or the total
ludmilkaskok [199]

Hey There!

Cross multiply on both sides, with this you will be cross multiplying in order to set the numbers up.

s * 2.4 = 2.4s

2.8 * 6 = 16.8

2.4s = 16.8

Divide s from both sides:

16.8/2.4

<u>The answer is 7 or s= 7</u>
