Think About the Process A sphere has a diameter of 56 ft. What should be the first step to find the surface area of the sphere? What is the surface area? Use 3.14 for pie.
(Type an integer or decimal rounded to the nearest hundredth as needed.)
The first step to find the surface area of a sphere would be to calculate the radius. The radius (r) can be found by dividing the diameter (d) by 2:
r = d/2 = 56 ft / 2 = 28 ft.
The surface area of a sphere can be calculated using the formula:
Surface Area = 4πr²,
where π is approximately equal to 3.14.
Therefore, the surface area of the sphere would be:
Surface Area = 4 * 3.14 * (28 ft)² = 4 * 3.14 * 784 ft² ≈ 3,097.92 ft².
Hence, the surface area of the sphere is approximately 3,097.92 square feet.
