The formula for finding the area of a circle is
a = pi × radius^2
Since the diameter is 14 inches, the radius is 7 inches, so to solve...
a = pi × 7^2
a = 3.14 × 49
a = 153.86
Rounded to the nearest tenth...
153.9 inches^2
Answer:
51 degrees
Step-by-step explanation:=Given data
Temperature at 6pm = 60 degrees
percent drop= 15%
= 15/100*60
=0.15*60
=9 degrees
Hence the temperature at 10 pm is 60-9= 51 degrees
Answer:The baker can make 144 croissants
Step-by-step explanation:
Lets solve your question
Divide the total amount of lbs of dough (18 lbs) by the total amount of dough for each croissant (1/8 lbs)
First divide 18(lbs) by 1/8 (lbs)
18/1/8= 18*8=144 croissants
The equation will be of the form:

where A is the amount after t hours, and r is the decay constant.
To find the value of r, we plug the given values into the equation, giving:

Rearranging and taking natural logs of both sides, we get:


The required model is:
