The volume of a sphere is 4/3(pi)r^3
To find the radius we do the diameter divided by 2 - 165/2=82.5
4/3(pi)(82.5)^3
We get 2,350,879 when we multiply it together, so your answer is 2,350,879 ft^3
The slope is 3, and the y-intercept is 9

Answer:
x = 1
Step-by-step explanation:
3(x + 6) -5 = 16
You want to first add the 5 (*flipping the sign) over to the 16
making your equation ...
3(x +6) = 21
Then you want to distribute the 3 to x and 6
making you equation
3x + 18 = 21
Then you want to subtract the 18 (*flipping the sign) to the right side
making the equation....
3x = 3
Lastly, divide the 3 on the left to the 3 on the right making the answer 1
x = 1
