The area of a circle with radius of 5 feet is 25π square feet
Step-by-step explanation:
The area of a circle is found out using the formula
Here A is the area
r is the radius of the circle and
pi is a constant
given
Radius = r = 5
We have to find the area in terms of pi
So,
Hence,
The area of a circle with radius of 5 feet is 25π square feet

As I understand, in this exercise, we have the following numbers:
By using calculator, let's convert those numbers into decimal form:
So arranging from least to greatest we have:
Put another way:
We have been given that a particular type of cell increases by 75% in number every hour. We are asked to find the number of cells present at the end of 12 hours if there are initially 4 of these cells.
We will use exponential growth formula to solve our given problem.
, where,
y = Final amount,
a = Initial amount,
r = Growth rate in decimal form,
x = Time.
Upon substituting initial value and
in above formula, we will get:
Therefore, there will be approximately 3300 cells at the end of 12 hours.
