Hi! To find the surface area of a cylinder, you need to find the surface area of the base, and then the surface area of the rectangular prism that "wraps around" the cylinder.
The area of a circle: A=pi*r^2
A=3.14*3.7^2
A≈43.00
Multiply this by 2 because there are 2 circles
Combined Area of Circles = 86
Circumference of a circle = C=2pi*r (this is for the width of the rectangle)
C=2(3.14)(3.7)
C=23.236
C=W
W=23.236
W*L=A
23.236 * 7.1=A
A≈165
Now lets add them together!
86cm^2+165cm^2= 251 cm squared
To take out terms outside the radical we need to divide the power of the term by the index of the radical; the quotient will be the power of the term outside the radical, and the remainder will be the power of the term inside the radical.
First, lets factor 8:
Now we can divide the power of the term, 3, by the index of the radical 2:
= 1 with a remainder of 1
Next, lets do the same for our second term
:
= 3 with a remainder of 1
Again, lets do the same for our third term
:
with no remainder, so this term will come out completely.
Finally, lets take our terms out of the radical:
We can conclude that the correct answer is the third one.
Answer:
72/8 = 9 pages
Step-by-step explanation:
Jenny has a total of 72 stickers, and uses 8 per page. By dividing 72 by 8 you will get the number of pages.
72 stickers/ 8 stickers per page = 9 pages used
