A quarter has a diameter of approximately 24 millimeters. What is the approximate area of the quarter ?
Answer choices:
75.36 mm square
452.16 mm square
150.72 mm square
1,808.64 mm square
Step-by-step explanation: The formula for area is A=πr². The radius is half of the diameter, which would give us 12. so just plug in. 12² is 144. 144π is 452.38. (Which is close to 452.16) Hope this helps :)
