4+15+11+5+7+10= 50 cm
10cm was the missing one
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

Step-by-step explanation:

Answer:
8.8 inches
Step-by-step explanation:
Since the level is proportional to the time, when the time increases from 5 to 11 (by a factor of 11/5), we expect the water level to increase by a factor of 11/5 to ...
(4 in) · 11/5 = 44/5 in = 8 4/5 in
