Find the area of the circle with a circumference of
30
π
. Use 3.14 for
π
. Round to the nearest hundredth.
Area in in decimal form: ______
Options:
Answers
Answer:
706.50 mm^2
Step-by-step explanation:
The formula to find the circumference is 2πr (r : radius)
if the circumference is 30π the the radius is = 15
to find the area we use the following formula :
π*r^2
r = 15 and π is given as 3.14
(3.14)*15^2 = 706.50 mm^2

Answer:
Use the referent of an adult stride (about 1 yard) to measure the dimensions of the area that will be covered by sod. Use the dimensions to calculate the area in square yards.
Step-by-step explanation:
This seems to be a relatively vague question, but it was requested so I'll try my best.
There's practically no way to accurately measure the area to be covered by sod without using a reference. I couldn't help but notice the list of references above the question, and I presume they are correlated. Since the length of an adult stride is 1 yard, you can use an adult stride as a reference to relatively accurately measure the dimensions of the area that needs to be covered. The method to find the area varies with the shape of the area, but assuming you can accurately find the area, this is a plausible way to estimate the area needed to be covered by sod. As an alternative, since the question stipulates sod can only be purchased in square yards or square meters, you can use a doorway (about 2 meters) in the list of references above the question to also measure the dimensions of the area. This is less practical because an adult stride is more mobile than a door.

UPDATE- IT'S 5.2
Answers
Answer: ≈ 5.2
Step-by-step explanation:
You're gonna want to use the Law of Cosines to solve:
c² = a² + b² -2abcos(R)
c² = 6² + 9² - 2(6)(9)cos(34°)
c² = 36 + 81 - 108cos(34°)
c² = 117 - 108(.82904)
c² = 27.46368
√c² = √27.46368 => 5.2405 = 5.2

Select the correct answer. The sum of two numbers is -18. If the first number is 10, which equation represents this situation, and what is the second number? A. The equation that represents this situation is 10 − x = -18. The second number is 28. B. The equation that represents this situation is 10 + x = -18. The second number is -28. C. The equation that represents this situation is x − 10 = -18. The second number is -8. D. The equation that represents this situation is -10 + x = -18. The second number is -8.
Answers
Answer:-28
Step-by-step explanation:
Let A is the second number

And we want to find:
[tex](f+g)(x)[/tex]
This is equivalent to:
[tex]=f(x)+g(x)[/tex]
Substitute:
[tex]=(4x+5)+(x^2-2x-2)[/tex]
Rearrange:

What you wrote below the top line and the bottom line are not the same thing.
I think you really want the second line, but one can't be sure.
(1*2 + 5)/2 div (9/8)
7/2 // 9/8
7/2 * 8*9
7*8/18 = 56/18 = 28/9
If you really do want the top line (the latex) it is different.
1 2/5 div (8/9) Is there such a thing as tfrac? I didn't know this but there is.
(1*5 + 2)5 // (8/9)
7/5 // 8/9 Invert the bottom fraction and multiply
7/5 * 9 / 8

What is the solution of -17 = -2y + 13 – 8y?
Answers
Answer:
3
Step-by-step explanation:
-17 = -2y + 13 - 8y
-17 = -10y + 13
-30 = -10y
3 = y
y = 3
Answer:
y = 3
Step-by-step explanation:
- 17 = - 2y + 13 - 8y
- 10y + 13 = - 17
- 10y + 13 - 13 = - 17 - 13
- 10y = - 30
- 10y ÷ - 10 = - 30 ÷ - 10
