Answer:
125π ft²
Step-by-step explanation:
1/4π(30)² - 1/4π(20)² = 125π
We know that Marcus spent 10 hours on his homework this week so:
10 hours = 100%
Marcus is saying that he spent 110% more time doing his homework this week, in comparison to last week.
Then to see if he is correct we have to find 110% of 10 hours.
So if: 100% of 10 hours = 10 hours
And: 10% of 10 hours (equivalent to 600 minutes) = 1 hour (or 60 minutes)
Then we add the two: 10 hours + 1 hour
And we get: 11 hours
As a result, Marcus is correct; he did spend 110% more time on his homework this week.
Hope this helps! :D
