The area that Jane needs to buy mulch for is approximately 753.9 square yards.
How to find the area of the garden
To find the area of the garden that Jane needs to buy mulch for, use the formula for the area of a circle.
The formula for the area of a circle is given by:
Area = π *

where π is approximately 3.14159 and r is the radius of the circle.
Given that the radius of the garden is 15.5 yards, we can substitute this value into the formula:
Area = 3.14159 *

Area ≈ 3.14159 * 240.25 ≈ 753.982
Rounding to the nearest tenth, the area that Jane needs to buy mulch for is approximately 753.9 square yards.
