Question:

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

Surface area = 4πr2;

where r is the radius of the sphere;

π is a constant that is roughly equal to 3.

Calculate the surface area of a sphere with a radius of 5 meters using the simple approximation above.

The surface area of a sphere with a radius of 5 meters 300

Explanation:

Given:

Radius of the circle = 5 metres

the value of is approximately = 3

To Find:

Surface area of the sphere =?

Solution:

The surface area of the sphere can be calculated using the below formula,

Surface area =

so now substituting the given values

Surface area =

Surface area =

Surface area = 300

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.
