Answer:
100 pi (314.16)
Step-by-step explanation:
Because the diameter is 20 in, that makes the radius = 20/2 inches = 10 inches.
10^2 * pi = area
100 pi = area
314.16 is approx. area.
The median of the trapezoid is the average of the bases. If we draw the trapezoid that is being described in this item, we will deduce that AB and DC are the bases and EF is given to be the median.
For this item,
EF = (AB + CD) / 2
Part A:
EF = (15 + 11) / 2 = 13
Part B:
AB = 2EF - CD
AB = (2)(14) - 10 = 18
Part C:
18 = ((5n - 9) + (2n + 3))/2
18 = (7n - 6) / 2
n = 6
Part D:
2y + 4 = ((5y + 2) + (-3y + 8))/2
y = 1
EF = 2(1) + 4 = 6
AB = (5(1) + 2 = 7
AB = -3(1) + 8 = 5
I used a calculator.
3.78/ 4.2 = 0.9
Answer: 0.9
Answer:
70 yards.
Step-by-step explanation:
50% is also 1/2, so you put 140/2, and get 70.
