What is the surface area of a sphere with a radius of 5.8 cm?
465.0 cm2
507.3 cm²
422.7 cm²
380.5 cm²
The formula to calculate the surface area of a sphere is given by:
Surface area = 4πr^2
Substituting the given radius of 5.8 cm into the formula:
Surface area = 4π(5.8)^2
Surface area ≈ 4π(33.64)
Surface area ≈ 133.856π
Using an approximation of π as 3.14159:
Surface area ≈ 133.856 × 3.14159
Surface area ≈ 420.611 cm²
Rounding to the nearest tenth, the surface area of the sphere is approximately 420.6 cm².
Therefore, the closest answer choice is 422.7 cm².
