The circumference is πd, and the diameter is 10, so the circumference is 10π. All sides of a square are equal, so the length of each side is 10π/4, which is 2.5π.
The length of each side of the square is 2.5π
Answer:
8
Step-by-step explanation:
Total pints of paint = 20
For landscape :
2/5 * 20 = 8 pints
For clover :
3/10 * 20 = 6 pints
Total used = (8 + 6) = 14
Pints left = 20 - 14 = 6 pints
14 required for next painting
14 - 6 = 8 pints
8 more pints needed

Answer:</h2>
The ratio of the area of region R to the area of region S is:

<h2>
Step-by-step explanation:</h2>
The sides of R are in the ratio : 2:3
Let the length of R be: 2x
and the width of R be: 3x
i.e. The perimeter of R is given by:

( Since, the perimeter of a rectangle with length L and breadth or width B is given by:
)
Hence, we get:

i.e.

Also, let " s " denote the side of the square region.
We know that the perimeter of a square with side " s " is given by:

Now, it is given that:
The perimeters of square region S and rectangular region R are equal.
i.e.

Now, we know that the area of a square is given by:

and

Hence, we get:

and

i.e.

Hence,
Ratio of the area of region R to the area of region S is:

Answer: At least 713 paintballs
Step-by-step explanation:
Based on the information that has been given in the question, the inequality that'll be used to solve the question will be:
18+0.08B≥75
0.08B≥75-18
0.08B≥57
B≥57/0.08
B≥712.5
Carolina needs to buy at least 713 paintballs along with the entrance fee to get the promotion.
Answer:
228
Step-by-step explanation:
We are adding 3 each time so general rule is
Tn= 3n + 3
Therefore
T= 3(75)+3
= 228
