Surface area=4πr²

dа ta:

π≈3

r=5 m

Therefore:

Surface area=4πr²=4 (3) (5 m) ²=300 m²

Answer: surface area = 300 m²

Surface area = 4πr2;where r is the radius of the sphere;π is a constant that is roughly equal to 3.Using the simple approximation above, calculate the surface area of a sphere with a radius of 5 meters.
