Question

Find the radius and the volume of of sphere whose Surface Area is 154sq.cm ​

Answer 1

Answer:

r≈7

Step-by-step explanation:

                      π=3.14 or $\frac{22}{7}$  I means  π during

=  r=$\sqrt[]{\frac{A}{π} }$                        

=  so it wil we be $\sqrt[]{\frac{154}{3.14} }$

=   7

therefore radius is 7
