Given, sphere
Radius (r) = 10 cm
Required to find : The ratio of the surface area to the volume
⇒4πr² : 4/3 πr³
⇒4 × (22/7) ×10cm ×10cm  :  (4/3)×(22/7)×10cm×10cm×10cm
⇒8800/7  :   88000/21
⇒1257.14  :   4190.4
∴The ratio is
 1257.14  :  4190.4

Ratio of area to volume of sphere=4π r²:4/3 π r³
after cancellation of 4π r² on both sides,
1:r/3
=3:10
