Given:
Diameter = 12 in
Diameter = 2r
Radius = D/2
Radius = 12/2 in
Radius = 6 in
Determine the area of the circle.
Formula for the area of the circle:
A = π r²
Solution:
Substitute the given value of the radius to the formula for the are of the circle.
A = π r²
A = π (6 in)^2
A = 36 π in^2
A = 113.1 in^2
Final answer:
A = 113.1 in^2
