Calculation of Surface Area of a Sphere

To calculate the surface area of a sphere, we can use the formula:

Surface Area = 4πr^2

where: - Surface Area is the total area covered by the surface of the sphere, - π (pi) is a mathematical constant approximately equal to 3.14159, - r is the radius of the sphere.

In this case, the radius of the sphere is given as √2 cm, and the point A is located at a distance of 1.5 cm from the center of the sphere.

Calculation Steps

1. Calculate the radius of the sphere using the given information: - The radius of the sphere is given as √2 cm.

2. Calculate the surface area of the sphere using the formula: - Surface Area = 4πr^2, where r is the radius of the sphere.

Calculation

1. Calculate the radius of the sphere: - Given: Radius = √2 cm

2. Calculate the surface area of the sphere: - Surface Area = 4π(√2)^2 - Surface Area = 4π * 2 - Surface Area = 8π

Answer

The surface area of the sphere is 8π square centimeters.

Please note that the exact numerical value of the surface area depends on the value of π, which is an irrational number.
