The formula for the area of a circle is:
A = πr^2
We are given that the radius of Jayden's circular garden is 15 yards. Therefore, we can plug this value into the formula to find the area:
A = π(15)^2
A = 225π
To round the answer to the nearest whole number, we need to approximate the value of π. Using 3.14 as an approximation for π, we can calculate the approximate area:
A ≈ 225(3.14)
A ≈ 706.5
Rounding to the nearest whole number, we get:
Jayden will need to cover a total area of about 707 square yards.
