a result of global warming is that the ice of some glaciours is melting .12 years after ice diappears tiny plants called lichens,start to grow on rocks.each lichens grow approx the shape of a circle .the relation ship b/w the diameter of a circle and age of lichens can be approxmated with formula d=13*(t-11) for t>11.whre d represents the diameter of lichens in millimeter ,and t repesents the years of of ice disappeared .using the formula calculate the diameter of lichen , 36 years after ice diappeared?
options
a) 468 mm
b) 457 mm
c) 325 mm
d) 11 mm

• d=13*(t-11)
  =13*(36-11)=13*25=325

• Just substitute it
  325mm

• t-36 substitute in formula we get answer

• As its given that aftr 12 years of ice disappearing lichens start to grow. so we might possibly have to deduct 12 from 36 and then use it in the formulae. but then ans wont match . :(
