Answer:
(5, 20)
Step-by-step explanation:
Find the surface area of her notebook.
30 + 30 + 20 + 20 = 100
Now find the surface area of the square stickers.
2 + 2 + 2 + 2 = 8
So this is the surface area of one square, now multiply it by 8.
8 * 7 = 56
This is the surface area of all the stickers, now subtract it to the surface area of the notebook:
100 - 56 = 44
So 44 centimeters of the notebook cover will still be showing.
You would use 1.73 in order to decrease an amount by 73%
Answer:
do it
Step-by-step explanation:
can determine that 8 is more than -9 by looking which one is more further to the right, since I see 8 I assume it is 8 and that would be correct
Here you'll need to do some online research, using "area of a cone" as your search term. There is a formula! But it's complicated.
Once you've found this formula online, substitute 17 feet for r. The height of the cone has to be calculated from the slant height (these are not the same):
(slant height)^2 = (12 feet)^2 = r^2 + h^2, where h is the actual height of the cone.
The area of the base is pi*r^2, or pi*17^2 square feet.
