Question

Find the volume and surface area of a sphere of radius is 42 cm

Answer 1

Step-by-step explanation:

using the formula of volume and surface area of sphere yourself you solve this question it is very easy questions you solve question

Answer 2

Answer:

Volume of sphere =4/3 ×pi ×radius cube

As we know radius =42

Therefore

Volume of sphere = 4/3×22/7×42×42×42= 310,464cm³

So, volume of sphere is equal to = 310,464 cm³

Now, to find surface area of sphere =4× pi× radius²

Therefore

Surface area of sphere = 4×22/7×42×42= 22176 cm²

Now

Volume of sphere = 310464cm³

And

Surface area of sphere = 22176 cm³
