Answer 2

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.

Answer:

The surface area of a sphere with a radius of 5 meters 300
`cm^2`

Step-by-step explanation:

Given:

Radius of the circle = 5 metres

the value of
`\pi` 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 =
`4\pi r^2`

so now substituting the given values

Surface area =
`4* (3)* (5)^2`

Surface area =
`4* (3)* (25)`

Surface area = 300
`cm^2`
