The result of global warming is the ice of some glaciers is melting. 19 years after the ice disappears, tiny planets, called lichens, start to grow on the rock. Each lichen grows approximately in the shape of a circle. The relationship between the diameter of the circle and the age of the lichen can be approximated with the formula: d =12* (t-19) for t>19, where d represents the diameter of the lichen in millimeters, and t represents the number of years after the ice has disappeared. Using the above formula, calculate the diameter of the lichen, 32 years after the ice has disappeared.

• Diameter of the lichen = 156
  
  t = 32
  => d = 12 *(32-19)
  => d = 12 *13
  => 156

• the diameter =156
  t=32 years
  d=12*(t-19)
  =>d=12*(32-19)
  =>d=12*13
  =>156
  d=156
