Answer:
2232.36m
Explanation:
since the perimeter of two semicircles adds up to that of one circle, the perimeter of the track would be the perimeter of the circle + the length of the rectangle.
we can find the perimeter of the circle using the formula of π × diameter, which would be:
π × diameter
= 3.14 × 74
= 232.36
now, we can add this to the given length of the rectangle:
232.36 + 1000 + 1000 = 2232.36
thus, the perimeter of the track is <u>2232.36m</u>.
i hope this helps! :D
Answer:
96, 672 yards
Step-by-step explanation:
Volume = Length · width · height
Volume = 114 · 212 · 4
Volume = 96, 672 yards

Answer:
10 miles.
Step-by-step explanation:
Let x be the number of miles on Henry's longest race.
We have been given that Henry ran five races, each of which was a different positive integer number of miles.
We can set an equation for the average of races as:
As distance covered in each race is a different positive integer, so let his first four races be 1, 2, 3, 4.
Now let us substitute the distances of 5 races as:
Let us multiply both sides of our equation by 5.
Let us subtract 10 from both sides of our equation.
Therefore, the maximum possible distance of Henry's longest race is 10 miles.
