Question

How do you find the surface area of the sphere in terms π given $s = 4\pi {r^2}$ and $r = 2.4$m?

Answer 1

Hint: In the given question, we have been given to evaluate the value of surface area of the sphere in terms π . We have been given that in the given scenario, we have the radius of the sphere. Using the value of the radius, we have to calculate the sphere.to do that, we write the standard formula of the sphere.

Formula used:
We are going to use the formula of surface area of the sphere whose radius is r:
$s = 4\pi {r^2}$

Complete step by step solution:
Here, the surface area of the sphere will be calculate by using this equation:
$s = 4\pi {r^2}$
Now, radius of the sphere is given in this question that is $r = 2.4$m
So substituting the value of radius in the equation of surface area of the sphere we get,
$ \Rightarrow s = 4\pi {(2.4)^2} = 23.04\pi {m^2}$

The surface area of the sphere in terms π is $23.04\pi {m^2}$

Note:
Here if you know the formula of the surface area of the sphere then these types of questions became very easy for you to solve. so remember the formula of the surface area of the sphere. here
We need to write the answer in terms of π so if you put the value of π then your answer will be wrong.
