The surface area of a sphere can be approximated as follows:

Surface area = 4tr2

where r is the radius of the sphere;

it 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 2 meters.

O A. 16 m2

O B. 24 m2

O C. 9 m2

O D. 48 m2

    The surface area of a sphere = 48 ²

    Explanation:

    Given:

    The radius of a sphere = 2 meters

    Use π = 3 (Approx)

    Find:

    The surface area of a sphere.

    Computation:

    ⇒ The surface area of a sphere = 4πr²

    ⇒ The surface area of a sphere = 4 (3) (2) ²

    ⇒ The surface area of a sphere = 4 (3) (4)

    ⇒ The surface area of a sphere = 48 meter²
