Final answer:
The area of each cookie is 254.3 square centimeters when calculated using the formula for the area of a circle with a radius of 9 centimeters and pi approximated as 3.14, rounded to the nearest tenth.
Step-by-step explanation:
To find the area of each cookie, which is a circle, you use the formula for the area of a circle: A = πr². In this case, the radius (r) is given as 9 centimeters, and you're asked to use 3.14 as an approximation for π (pi). Substituting the values into the formula, we get: A = 3.14 × (9 cm)² = 3.14 × 81 cm² = 254.34 cm². When rounded to the nearest tenth, this gives us an area of 254.3 square centimeters.
