We are given square with side length l. The largest circle that we can cut from that square has diameter equal to that side. This circle is called inscribed circle.
When cutting circle from square paper we will be left with some extra paper. Area of that extra paper can be calculated using formula:
area_of_extra_paper = area_of_square - area_of_circle
Now we can insert formulas:

This is area of extra paper when we cut one circle. When we cut multiple circles we have:

Where:
N = number of circles
This formula is roughly:
The answer is 105 because 180-75=105
Answer:
6.75.
Step-by-step explanation:
Following PEMDAS, as there are no other variables, we move from right to left. 9 x 3 is 27, and 27 / 4 is 6.75.
Hope this helps!
Answer:
Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named as Perpendicular, Base and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle 90°.
Hi! So this question is just finding area in a more complex way. To solve for the area of the entire shape, you can break it down into 3 smaller shapes. The area of the triangle at the top would be equal to (1/2)(8)(15). The area of the small rectangle would be (15)(20) since you subtract the 10 yds from 30 yds to find that side. The area of the big rectangle would be (20)(30). After calculating all of these smaller shapes, you add them together, divide by 35 to find how many gallons you need, and make sure to round up because you can't buy half a gallon! (Your answer should come out to 28)
