Answer:
Area = 1134 in^2
Explanation:
Formula for the area of a circle:
The formula for the area of a circle is given by:
A = πr^2, where:
- A is the area in units squared,
- and r is the radius.
The radius is simply 1/2 the diameter (d):
r = 1/2d
Finding the radius:
Now, we can find the radius by halving :
r = 1/2(38)
r = 19
Thus, the radius is 19 inches.
Finding the area:
Now, we can find the area by substituting 19 for r in the formula for the area of a circle:
A = (π)(19)^2
A = (π)(361)
A = 1134.114948
A = 1134
Therefore, the area of the circle is about 1134 in^2
