For this case we must find the area of the cookie, knowing that it has a circular shape. By definition, the area of a circle is given by:
Where:
r: It is the radius of the circle
According to the data we have:
Thus, the area of the cookie is:
We have 
We round:
Thus, the area of the cookie is 
Answer:
Fraction = 3/7
decimal = approximately 0.429
percentage = approximately 42.86%
Answer:
total surface area = 298.45105 m2
lateral surface area = 141.37155 m2
top surface area = 78.53975 m2
bottom surface area = 78.53975 m2
Step-by-step explanation:
The solution to the problem is as follows:
x^3-x^2 +x -1= x^2(x-1) +(x-1)=(x-1)(x^2+1) ,(common factor x-1
<span>
(x^2-1)=(x-1)(x+1) </span>
<span>
LCM=(x-1)(x^2+1)(x+1) </span>
<span>
=(x^2-1)(x^2+1)=x^4-1
I hope my answer has come to your help. God bless and have a nice day ahead!
