Answer:
Step-by-step explanation:
You need to set up a proportion
Let x = NK
7/13 = x/56 Notice that the longest side of the small trapezoid is the denominator of the fraction on the left. That means that the longest side of the large trapezoid must also be the denominator of that fraction on the right.
Cross multiply
13x = 7*56 Combine the right
13x = 392 Divide by 13
x = 392/13
x = 30.15
NK = 30.15
Answer:
The first answer, 3(pi) km^2
Step-by-step explanation:
3 x pi squared determines the area
11 and 12.
the square of 11 is 121 and the square of 12 is 144 and because 140 is between 121 and 144, 11 and 12 are the correct answer.
