Final answer:
The area of circle 'b' with a radius of 3.00 yards is 9.00π yd². This is calculated using the formula A = πr² and keeping the result in terms of π.
Step-by-step explanation:
To find the area of a circle in terms of π, you can use the formula A = πr², where 'A' is the area and 'r' is the radius of the circle. Suppose the radius of the circle 'b' is given as 3.00 yards. Using the formula, we'd calculate the area as A = π(3.00 yd)².
After squaring the radius, the calculation would be A = π(9.00 yd²), which simplifies to A = 9.00π yd². This gives us the area of circle 'b' in terms of π without using a numerical approximation for π.
It's important to note that if precision is needed beyond the significance of the given measurements, we would limit the calculated area to the number of significant figures from the measurements provided, which in this case is two. However, since we are leaving the answer in terms of π, significant figures do not need to be considered until π is approximated numerically.
