3x + 4(x + 1) = 67
7x + 4 = 67
7x = 67-4 = 63
x = 9
The smaller integer is 9.
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
Answer: 1 hour 20 minutes
Step-by-step explanation:
Given : The old machine could shred a truckload of paper in 4 hours.
Rate of work done by old machine = 
The new machine could shred the same truckload in 2 hours.
Rate of work done by new machine = 
Let 't' be the time taken by both of them working together , then we have the following equation:-

Since 1 hour = 60 minutes
Then, 
Hence, it will take 1 hour 20 minutes to shred the same truckload of paper if Ron runs both shredders at the same time.
