Final answer:

The approximate surface area of the sphere is 2826 square yards.

Step-by-step explanation:

The surface area of a sphere can be calculated using the formula:

Surface Area = 4πr²

where r is the radius of the sphere.

In this case, the radius is given as 15 yards. So, substituting the value of r into the formula:

Surface Area = 4π(15)²

Surface Area ≈ 4π(225)

Surface Area ≈ 900π

Using the approximate value of π = 3.14, we can calculate the surface area.

Surface Area ≈ 900(3.14)

Surface Area ≈ 2826 square yards

The surface area of a sphere is equal to [4 x Pi x R^2]. In other words, four multiplied by 3.14 multiplied by the radius squared. If the radius of a sphere is 15 yards, the approximate surface area is [4 x 3.14 x (15x15)] = [12.5 x 225] = [2,812 yd^2]. The surface area of a sphere with radius 15 yd is approximately 2,800 yards.
