Answer:
$44
Step-by-step explanation:
First, find how much he was making originally:
Multiply the number of hours he worked by the amount he got per hour:
20(8)
= 160
Then, find how much he gets now:
24(8.50)
= 204
To find his total weekly pay increase, find the difference between them:
204 - 160
= 44
So, his total weekly pay increase is $44

Surface area of sphere is 
Step-by-step explanation:
We need to find the surface area of the sphere while we are given volume of sphere = 972π
The formula used to find surface area is:

We need to find radius of sphere
We are given Volume = 972π, using this volume we can find radius of sphere
The formula used to find volume is:

Putting values and finding r


Taking cube root on both sides
![\sqrt[3]{r^3}=\sqrt[3]{729}\\ r=9](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Br%5E3%7D%3D%5Csqrt%5B3%5D%7B729%7D%5C%5C%20r%3D9)
So, Radius of sphere r=9
Now finding surface area:




So, surface area of sphere is
