Answer: The area of the cross section is 81pi meters.
Since we are given the circumference, we can write and solve an equation about the diameter.
C = pi(d)
18pi = pi(d)
18 = d
Since the diameter is 18, the radius is half of that or 9 meters.
Now, plug 9 as the radius into the area formula.
A = pi(r^2)
A = pi(9^2)
A = 81pi
0.15 * 100 = 15
Answer: 15 times in 100
19.184*0.46=8.82464 the answer is: 8.82464
Answer:
x=9
Step-by-step explanation:
-3 is the slope, use y2 - y1 over x2 - x1 equation to solve
