Answer:
The answer to your questions radius = 14 in
Step-by-step explanation:
Data
Circumference = 28π in
radius = ?
Circumference is defined as the distance around the edge of a circle.
Formula
Circumference = 2π radius
-Solve for radius
radius = Circumference /2π
-Substitution
radius = 28π / 2π
-Simplification
radius = 28/2
-Result
radius = 14 in
Answer:
Step-by-step explanation:

Newton's Law of cooling is a differential equation that is simplified by using limits in temperature and time. The simplified equation is:
ln(T-Ts) = ln(T0-Ts) - kt
where
T is the final temperature
T0 is the initial temperature
Ts is the temperature of the surroundings
t is the time
k is a constant
Substituting the values:
ln(T-70) = ln(200-70) - (0.6)(2)
T = 109.16°F
The answer is B.
