A thermometer is removed from a room where the temperature is 70° F and is taken outside, where the air temperature is 40° F. After one-half minute the thermometer reads 60° F. What is the reading of the thermometer at t = 1 min? (Round your answer to two decimal places.)

53.3324

Step-by-step explanation:

given that a  thermometer is removed from a room where the temperature is 70° F and is taken outside, where the air temperature is 40° F.

By Newton law of cooling we have

T(t) =

where T (t) is temperature at time t,T =surrounding temperature = 40, T0 =70 = initial temperature

After half minute thermometer reads 60° F. Using this we can find k

So equation is

When t=1,

we get

true

explanation:

d.) yes, because the volume of the cone is greater than the volume of the sphere
