Answer:
(200π - 12)ft
or
616.32 ft
Step-by-step explanation:
Given in the question,
there are four circle around which corn will be planted.
radius of first circle = 10 ft
radius of second circle = 20 ft
radius of third circle = 30 ft
radius of fourth circle = 40ft
circumference = 2πr
First circle
2π(10)-3
20π -3
Second circle
2π(20)-3
40π-3
Third circle
2π(30)-3
60π-3
Fourth circle
2π(40)-3
80π-3
Add them up
80π - 3 + 60π - 3 + 40π - 3 + 20π - 3
(200π - 12)ft
or
616.32 ft

Answer:
x=56
Step-by-step explanation:
Answer: The running speed of Elena is 5 miles/hour and this can be determined by using the formula of speed.
Step-by-step explanation:
A circular running track 1/4 is a mile long.
Elena runs on this track, completing each lap in 1/20 of an hour.
Speed formula is used to determine the speed of Elena. The formula of speed is given by:
----- (1)
where S is the speed, D is the distance and T is the time taken by Elena to run a circle.
Now, put the value of distance D and time T in the equation (1).
Speed = 5 miles/hour
Therefore, the running speed of Elena is 5 miles/hour.
