Answer:
216.66 yd²
Step-by-step explanation:
One way to find the area of a ring like this is to multiply its centerline length by the width of the ring.
Here, the diameter of the circle that is the centerline of the ring is 23 yd. The circumference of that circle is ...
C = πd = 3.14(23 yd) = 72.22 yd
Then the ring area is ...
(72.22 yd)(3 yd) = 216.66 yd² . . . area of shaded region
3/5 is bigger because 4/7 = 20/35 and 3/5 = 21/35
Answer:
T(x,y)->(x-3,y-6)
Step-by-step explanation:
Say we take point E and E1. To move E to E1, we need to move it to the left 3 units, already giving us x-3. Then, we need to find out how far down it moved. by counting the units, we can tell that it moved 6 units down as well, giving us y-6. In the end, we get T(x,y)->(x-3,y-6).

- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Set up Equation</u>
x + (x + 65) + 25 = 180
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 2x + 90 = 180
- Isolate <em>x</em> term: 2x = 90
- Isolate <em>x</em>: x = 45
