Answer:
A = 50.24 cm
Step-by-step explanation:
Area formula of a circle:
A = π r²
diameter- r+r
which means that your diameter(8) divided by 2 = 4
r of circle= 4
A= 3.14(4²)
A = 3.14(16)
A = 50.24 cm
Its 2.59%. i mean i figured it out and i got 2.59%

Answer: 0.8 radians
Step-by-step explanation:
To solve this exercise you must apply the formula shown below:
Where S is the arc lenght, r is the radius of the circle and 
is the central angle in radians.
Solve for the central angle:
Now, when you susbtitute the value of the arc length and the radius, you obtain that the central angle is:
To find the percent of anything, you divide what you have from the total (or the smaller number over the bigger number). In this case, you will do 14/26.
14/26=0.53846
I'm going to round to the hundredths: 0.54
Move the decimal place two times to the right: 54
The percent change from 14 inches to 26 inches is 54%
