Explanation:
Diameter = 3 inches
Area of a circle = pi(r)^2
r = radius
Diameter = radius(2) or diameter/2
3/2 = 1.5
Area = pi(1.5^2)
= 2.25pi
You can simplify your answer to 2.25(3.14) because pi = approximately 3.14
2.25(3.14) = 7.065
Because the question is looking for the combined area of the area of the mirror and frame (2.25pi), multiply the area of the mirror by area of the frame (2.25) to get your combined solution.
*Make sure to put the unit (square inches or sq. in.)
Answer:
2.25pi or 7.065
