Answer: 81pi square meters
--------------------------------------------------------
Work Shown
C = 18pi is the given circumference
d = diameter which is unknown
C = pi*d
18pi = pi*d
18 = d
d = 18
The diameter is 18 meters.
Half of this is the radius r = d/2 = 18/2 = 9
The radius is 9 meters
Use the value of r to find the area of the circle
A = pi*r^2
A = pi*9^2
A = pi*81
A = 81pi
The area of the circular cross section is 81pi square meters
The answer is 9 because 9x9=81. Hope this helps!
They are the same angle, so we can write an equation to resemble it.
2w - 5 = 95
Solution:
2w - 5 = 95
2w = 100
w = 50
Check:
2(50) - 5
100 - 5
95
Therefore, w = 50
Best of Luck!
x -2y = 2
3x +y = 6 multiplie both sides by 2 => 6x +2y = 12
x -2y = 2
6x +2y = 12
------------------- assum the same terms
7x 0 = 14
x = 14/7
x = 2
