4. 904.3 m2
The formula for surface area of a sphere is A = 4πr^2, where r is the radius of the sphere. Since the diameter is given, we can find the radius by dividing it by 2:
r = d/2 = 12/2 = 6 m
Substituting this value into the formula gives:
A = 4π(6^2) = 4π(36) = 144π ≈ 904.3 m2
Find the surface area of a sphere with a diameter of 12 m
1.452.2 m2
2. 150.7 m2
3. 113.0 m2
