Answer:
113.04 sq. in.
Step-by-step explanation:
If the diameter of the circle is 12", then the radius is 6" (half the diameter), and the area "A" is (approximately) 3.14 * 6^2. The calculation is approximate because 3.14 is a rounded value for pi.
Answer:
The area of the circle is 113.04in²
Step-by-step explanation:
radius = half of diameter
d = 12 in
r = 12in / 2 = 6in
To solve this problem we need to use the area formula of a circle:
a = area
r = radius = 6in
π = 3.14
a = π * r²
we replace with the known values
a = 3.14 * (6in)²
a = 3.14 * 36in²
a = 113.04in²
The area of the circle is 113.04in²
