volume and surface area
Give your answers to 3 significant figures
Take l = 3.142​

Answer 1

Answer:

Step-by-step explanation:

Volume of Sphere = 4/3  pi r ^3

                              = 4/3 * 3.14 * 12.6*12.6*12.6

                             = 1.3 * 3.14 * 12.6*12.6*12.6

                            = 8165.

Surface Area of Sphere =  4 pi r^2

                                       = 4 * 3.14 * 12.6*12.6*12.6

                                      = 25124
