Question

The largest possible sphere is carved out from a solid cube of side 40m. Fine the surface area of the sphere. Please answer fast with steps. Thanks.

Answer 1

 Diameter = 40m
∴ Radius (r) = 40/2 = 20m

∴ Surface area of sphere = 4πr² = 4*22*(20)²/7 = 5028.571 m²                                     i think this i hope it help u

Answer 2

Given - Side of the cube

Find - Surface area of the sphere

Solution - The surface area of the sphere will be 5026.5 metre²

The diameter of the sphere will be equal to the dimensions of the cube.

The surface area of the sphere is given by the formula - 4πr²

So, finding the radius of the sphere.

The radius of sphere = 40/2

The radius of sphere = 20 metres

The surface area of sphere = 4*π*20²

The surface area of sphere = 5026.5 metre²

The surface area of the sphere is 5026.5 metre².
