On planet zorba, a solar blast has melted the ice caps on its
equator. 8 years after the ice melts, tiny plantoids called echina start
growing on the rocks. echina grows in the form of a circle and the
relationship between the diameter of this circle and the age of echina
is given by the formula
d = 4 * sqrt (t – 8)for t = 8
Where the represents the diameter in mm and t the number of years since
the solar blast.
Jagan recorded the time of some echina at a particular spot is 24 years
then what is diameter?

-
- d = 4 * sqrt (t - 8)
d = 4 * sqrt (24 - 8)
d = 4 * sqrt (16)
d = 4 * 4
d = 16 - 11 years agoHelpfull: Yes(8) No(1)
- d = 4 * sqrt(t-8)
d = 16 as r= 8 given
thus 16 = 4 * sqrt(t-8)
4 = sqrt (t-8)
t-8 = 16
t = 24 - 12 years agoHelpfull: Yes(4) No(6)
