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
Answer:
21x³y
Step-by-step explanation:
Answer:
A = 1.77 ft^2
Step-by-step explanation:
The circle has a diameter of 1.5 ft
We need the radius
r = d/2 = 1.5/2 = .75 ft
The area of a circle is
A = pi r^2
A = 3.14 ( .75)^2 = 1.76625
To the nearest hundredth
A = 1.77 ft^2
