Hey mate here is your answer

Answer:

SA=5538.96 cm², Volume=38772.72 cm³

Step-by-step explanation:

diameter =42

so ,radius will  be half of it=21 cm

∴r=21 cm

now,

let us consider π=3.14

so now ,

volume of the beach ball=4/3 π r³

                                      =4/3*3.14*21³

                                      =now,

                                      =4*3.14*3087

                                      =38772.72 cm³

so now,

surface area of beach ball=4 π r²

                                        =4 * 3.14 *441

                                        =4 * 1384.74

                                        =5538.96 cm²

The volume of the beach  ball is 38772.72 cm³ and ,surface area of beach ball is 5538.96 cm²

Hope it helped you :)

Answer:

Diameter =42 cm

Radius =21 cm

Surface area of sphere = 4πr^2

= 4*22/7*21*21

= 4*22*21*3

= 5544cm ^2

Hope it help you ✌️❣️
