Final answer:
The area of a circle with a radius of 7.5 is calculated using the formula A = πr², which results in 176.71 when rounded to two decimal places, matching option A.
Step-by-step explanation:
The area of a circle is given by the formula A = πr², where A is the area, π (pi) is approximately 3.14159, and r is the radius of the circle.
To calculate the area of a circle with a radius of 7.5, you would use the formula:
A = π(7.5)^2
Plugging in the values gives:
A = 3.14159 × (7.5)^2
A = 3.14159 × 56.25
A = 176.7148125
When rounded to two decimal places, the area is approximately 176.71, which corresponds to option A.
