Answer:
25 yards
Step-by-step explanation:
radius is half of what the diameter is.
50 / 2 = 25
Answer:
463 rounded to the nearest hundred gives 500.
536 rounded to the nearest hundred gives 500.
556 rounded to the nearest hundred gives 600.
555 rounded to the nearest hundred gives 600.
445 rounded to the nearest hundred gives 400.
If you’re just multiplying then i guess you just multiply the three with all the numbers in the bracket, so 3,15,-15,18,0,0
Answer:
56π
Step-by-step explanation:
1. Approach
To find the radius of a circle, use the formula;
π
To find the area of the shaded region, find the area of the larger circle, and then subtract the area of the smaller circle from it.
It is given that the larger circle has a radius of 9, and the smaller has a radius of 5.
2. Area of the larger circle
π
Substitute in known value (use 3.14 for π)
![A = (9)^{2} * 3.14](https://tex.z-dn.net/?f=A%20%3D%20%289%29%5E%7B2%7D%20%2A%203.14)
A = 254.47
3. Area of the smaller circle
π
Substitute in known value (use 3.14 for π)
![A = (5)^{2} * 3.14](https://tex.z-dn.net/?f=A%20%3D%20%285%29%5E%7B2%7D%20%2A%203.14)
A = 78.54
4. Area of the shaded region
Subtract the area of the smaller circle from the area of the larger circle;
254.47 - 78.54 = 175.93
~ 56π
