Question

if a sphere of radius r is divided equally in four parts, the total surface area of the All Four Points will be​

Answer 1

Answer:

AREA OF SPHERE=4πr²

SO IT IS DIVIDED BY 4 EQUAL PARTS=4πr²÷4

                                                                =πr²

Surface are of two identical semicircular regions = 2*πr^2/2 = πr^2.

So, surface area of each part = 2πr^2.

Total surface area of all four parts = 8πr^2.
