10) On planet korba, a solar blast has melted the ice caps
on its equator. 9 years after the ice melts, tiny planetoids
called echina start growing on the rocks. Echina grows in
the form of circle, and the relationship between the
diameter of this circle and the age of echina is given by
the formula
d = 4*√ (t-9) for t ≥ 9
Where d represents the diameter in mm and t the number of
years since the solar blast.
Jagan recorded the radius of some echina at a particular
spot as 7mm. How many years back did the solar blast occur?
a) 17 b) 21.25 c) 12.25 d) 12.06
