Answer:
38 cm²
Explanation:
To find the area of a circle, we can use the formula A = πr², where A is the area, r is the radius of the circle, and π is approximately equal to 3.14.
Since the diameter of each button is 7 cm, the radius of each button is half the diameter, or 7/2 = 3.5 cm. We can plug this value into the formula to find the area of each button:
A = πr² = π * 3.5^2 = 3.14 * 12.25 = 38.1 cm²
The closest measurement to 38.1 cm² is 38 cm². Therefore, the area of each button is closest to 38 cm².
