18. What is the surface area of a sphere with a radius of 6 meters rounded to the nearest square meter?
O 226 m²
O 905 m²
O 113 m²
O 452 m²
The formula to find the surface area of a sphere is:
Surface Area = 4πr²
Where r is the radius of the sphere and π is a mathematical constant rounded to 3.14.
Using this formula and substituting r with 6 meters, we get:
Surface Area = 4 x 3.14 x 6²
Surface Area = 452.16 m²
Rounding it to the nearest square meter would give us:
Surface Area ≈ 452 m²
Therefore, the answer is (O) 452 m².
