Answer:
Area of the quarter is 452.16 mm²
Step-by-step explanation:
A quarter has a diameter of 24 mm approximately.
We have to calculate the area of the quarter.
Since area of a quarter = area of a circle = πr²
Where r is the radius
Since diameter of the quarter = 24 mm
Therefore radius =
Now we put the value of r = 12 mm to calculate the area
Area = (3.14)(12)²
= (3.14)(144)
= 452.16 mm²
Therefore Area of the quarter is 452.16 mm²

Given:-
Diameter=24mm
Hence, radius=24/2=12mm
Circumference of circle=2πr
=2×3.14×12
=75.36mm
Hence,measurement is closest to the circumference of the coin in millimeters is 75.36mm
