The average height of the fence is 2 m; its length is 20π m. So, its 2-sided area is
A = 2*(2 m)*(20π m) = 80π m² ≈ 251 m²
At 1 L/(100 m²), it will take 2.51 L of paint to paint both sides.
Answer:
10
Step-by-step explanation:
the sudents were put in 10 equal groups
10x6=60
C=2pir
V=(4/3)pir^3
solve for V
C=31.4
31.4=2pir
divide by 2
15.7=pir
divide both sides by pi or 3.14
5=r
V=(4/3)pir^3
V=(4/3)pi5^3
V=(4/3)pi125
V=(500/3)*3.14
V=523.33333333333333333333333333333
rounded
523 cubic inchs
Answer:
20 miles
Step-by-step explanation:
The formula for distance is
d =rt where r is the rate and t is the time
We need to convert the time to hours since the rate is in mph
15 minutes * 1 hour/ 60 minutes = 1/4 hour = .25 hours
d = (80 mph) * .25 hours
d = 20 miles
[6] ([3] + [50])
Just make sure you understand how to work backward with problems like this if you are ever confused. :)) good luck!!
