(1) circumference of a circle = 2π.R
(2) area of a circle = π.R²
Area = 452.16 m² (given), so we can calculate the radius:
452.16 = π.R²
452.16/π = R²
143.92 = R² → R =√143.92 ≈ 12 m
Having R = 12, now we can calculate the circumference :
circumference of a circle = 2π.R = 2.π.12 = 75.41 m
To answer this question, you would need a protractor, which is a device that measures angle. Because this is a picture, I cannot help you. I'm sorry....
What I can tell you is that the angle is less than 90 degrees.
Answer:
Yes
Step-by-step explanation:
The lines of symmetry are the three altitudes.
6:40pm Just add the minutes together to get 70 minutes that’s an hour and ten minutes then you get your answer
Answer: y = -5
Substitute in 3 for x.
x - y = 8 Substitution
3 - y = 8 Subtract 3 from both sides
-y = 5 Divide by -1 to both sides
y = -5 Answer!
You can also check your work.
x - y = 8
3 - (-5) = 8
3 + 5 = 8
8 = 8
