The area of the sports field is 10150 square meters and the length of one lap of the track is 400 meters.
<h3>What is the area of the rectangle?</h3>It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
Area of the sports field = area of the rectangle + area of the two semicircle
Area of the sports field = 90×70 + π(70/2)²
= 6300 + (22/7)1225
= 6300 + 3850
= 10150 square meters
Length of the track = perimeter of the rectangle + circumference of the
two-semi circle
= 90 + 90 + 2π(70/2)
= 180 + 70(22/7)
= 180 + 220
= 400 meters
Thus, the area of the sports field is 10150 square meters and the length of one lap of the track is 400 meters.

Answer:
V' = -0.11552 *V\\= -0.11552(1.8)\\ \\=-0.20794 million per year
Step-by-step explanation:
Given that oil is pumped continuously from a well at a rate proportional to the amount of oil left in the well. Initially there were 3 million barrels of oil in the well; six years later 1,500,000 barrels remain.
i.e. if V stands for volume of oil, then
To find A and k
V(0) = A = 3 million
Hence V =
V(6) = 1.5
i.e.
a) Using the above value of k , we have
million per year.
Answer:
5.
Step-by-step explanation:
==>>We would have to multiply the original amount by 1.50^x because the initial amount would be 1, and 50% increase would be .5 so 1.5 and you raise it to the number of years to show the total increase.
Initial: 10,000
After 1 year
10,000 + (.5*10000)
10,000 + 5000 = 15,000
--
After 2 years
15,000 + (.5*15000)
15,000 + 7500 = 22,500

Let's try our equation.
