Answer:
the correct answer is HLI
Given:
- Outer diameter = D = 80 ft
- Inner diameter = d = 40 ft
So,
Outer radius = R = D/2
=> R = (80 ft)/2
=> R = 40 ft
Inner radius = r = d/2
=> r = (40 ft)/2
=> r = 20 ft
Area of paved pathway = πR² - πr²
= π(R² - r²)
= π(R + r)(R - r)
= π(40 + 20)(40 - 20) ft²
= π(60)(20) ft²
= 3.14 * 1200 ft²
= 3768 ft²
Answer:
the factors of x^3-1 are 
Step-by-step explanation:
We need to find factors of x^3 -1
So, the factors of x^3-1 are
First, let's find how many page's Greta read per day. She read a total of 900 pages across 15 days, so she read:
900 pages / 15 days = 60 pages/day
Now we can find how many pages she read per hour by dividing the 60 pages per day by 5 hours:
60 / 5 = 12 pages/hour
The answer is 12 pages.
