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[tex]cm^2[/tex]
Explanation:
Given:
Radius of the circle = 5 metres
the value of [tex]\pi[/tex] 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 = [tex]4\pi r^2[/tex]
so now substituting the given values
Surface area =[tex]4\times (3)\times (5)^2[/tex]
Surface area =[tex]4\times (3)\times (25)[/tex]
Surface area = 300[tex]cm^2[/tex]
