Question

calculate mass of a sphere of radius 7 cm if its density is 1 gm/cm3​

Answer 1

Mass of the given sphere

is 1436.0267gm.

★Volume of a sphere =

$\frac{4}{3} \times \pi \times {(r)}^{3}$

$mass = density \times volume \\ mass = 1 \times \frac{4}{3} \pi \times {(7)}^{3} \\ mass = \frac{4 \times 3.14 \times 343}{3} \\ mass = \frac{4308.08}{3} = 1436.0267gm$

Answer 2

Answer:  1437.33 gm

Step-by-step explanation:

1. since radius of the sphere is given so we can find volume of sphere easily....                

        volume of sphere = 4/3πr³

                                       = 4/3 ×22/7×7×7×7

                                       =4312/3 cm³

     2. now since we have got the volume of the sphere an the density of            the sphere is already given , so now we can find the mass of the  sphere easily....

     we know,

                      Density = Mass / Volume

                       Mass = Density × Volume

                        Mass = 1 gm/ cm³× 4312/3 cm³

                                  = 1437.33 gm

and hence  I solved your question dude......hope u will like my answer and if so plzzz mark me as brainlist.....by the way I enjoyed your question.....thanks dude.....
