Question

Find the volume of sphere having radius
(1) 5.6 (2) 4.2 cm​

Answer 1

Step-by-step explanation:

1.735.62 and 2.310.34

Answer 2

Answer:

(1)   735.91 cu.cm

(2) 310.46 cu.cm

Step-by-step explanation:

(1) Volume of a sphere = $4\\ 3 \ \pi r^{3}$

                                     =4/3 x 22/7 x 5.6 x 5.6 x 5.6

                                     = 735.91 cu.cm

(2) Volume of a sphere = $4\\ 3 \ \pi r^{3}$

                                     =4/3 x 22/7 x 4.2 x 4.2 x 4.2

                                     = 310.46 cu.cm
