Question

Draw a circle of radius 8 can. Divide it into 4 equal parts. What is the name of each part?​

Answer 1

Step-by-step explanation:

First find the surface area of the sphere:

Surface area (sphere) = 4⋅π⋅r2

= 4⋅π⋅82 ,==> 256 π cm 2 or 804.2477193 cm 2

So, each part will have a curved surface area as:

= (256 π )/4 = 64 π cm 2 or 201.0619298 cm 2

Circle area = π⋅r2

= π⋅82

= 64 π cm 2

Each part will have (1/2) x 2 the circle’s surface area or one circle’s area:

Total surface area for each piece of sphere is:

64 π cm 2 + 64 π cm 2 = 128 π sq cm or 402.1238597 sq cm

>>>>>>>>>>>> 128 π sq cm or 402.1238597 sq cm
