7-1=6
1*6=6
6-1=5
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
Answer:
the second one
Step-by-step explanation:
Simply using the given formula ,
I = P × R × t
I = 100 × 10/100 × 3
I = $30
