Answer: 1 minute 34 seconds
Step-by-step explanation:
From the question, Frankie was practicing for a 5 kilometer race and his normal time is 31 minutes and 24 seconds but yesterday he used 29 minutes and 50 seconds. To calculate how much time came of his normal time, we are going to find the difference between the yesterday's time and normal time. This will be:
31 minutes 24 seconds - 29 minutes 50 seconds = 1 minute 34 seconds
Answer:
The area of the base is ![10\pi m^2](https://tex.z-dn.net/?f=10%5Cpi%20m%5E2)
Step-by-step explanation:
The volume of a cylinder is calculated using the formula:
![Volume=\pi r^2h](https://tex.z-dn.net/?f=Volume%3D%5Cpi%20r%5E2h)
The volume is given to be:
![V=140\pi m^3](https://tex.z-dn.net/?f=V%3D140%5Cpi%20m%5E3)
The height of the cylinder is h=14 meters.
We substitute these values into the formula to obtain;
![140\pi=\pi r^2\times 14](https://tex.z-dn.net/?f=140%5Cpi%3D%5Cpi%20r%5E2%5Ctimes%2014)
Divide both sides by 14.
![\frac{140\pi}{14}=\pi r^2](https://tex.z-dn.net/?f=%5Cfrac%7B140%5Cpi%7D%7B14%7D%3D%5Cpi%20r%5E2)
![10\pi=\pi r^2](https://tex.z-dn.net/?f=10%5Cpi%3D%5Cpi%20r%5E2)
The area of the base is a circle which is ![\pi r^2=10\pi m^2](https://tex.z-dn.net/?f=%5Cpi%20r%5E2%3D10%5Cpi%20m%5E2)
