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​

Respuesta :

Answer:

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
