A Sphere has a radius of 7 in, What is the surface area?
199
615
615.44 in squared
The surface area of a sphere can be calculated using the formula:
Surface Area = 4πr^2
Given that the radius (r) is 7 inches, we can substitute this value into the formula:
Surface Area = 4π(7^2)
Surface Area = 4π(49)
Surface Area = 196π
Using π ≈ 3.14, we can calculate the approximate surface area:
Surface Area ≈ 196(3.14)
Surface Area ≈ 615.44 in^2
Therefore, the surface area of the sphere is approximately 615.44 in^2.
