Answer:
2
Step-by-step explanation:
In this case, you have to substitute the w for -1, and then do the operation:
-6( -1 )^2 + 13( -1 ) + 21
-6( 1 ) - 13 +21
-6 -13 + 21
-19 + 21

Step-by-step explanation:
The puppy runs a distance of D) 18 - 19 meters in one lap.
Step-by-step explanation:
Step 1; It is given that the leash measures 3 meters long. He runs pulling the leash as much as he can creating circles. Even though he keeps pulling, the leash will remain at a constant length of 3 meters. So we need to calculate the perimeter of the circle.
Step 2; The perimeter of any given circle is 2π times the radius. The radius of this circle is equal to 3 meters.
Perimeter of the circle = 2π × r = 2 × 3.1415 × 3 meters = 18.85 meters.
So the puppy runs a distance of 18.85 meters in a lap.
1. Use the formula: A = π x r^2
2. Find the radius.
3. Multiply the radius by itself to square it.
4. Multiply the result by pi.
5. Use the result as your answer.
I feel like it would be 60 but I could be wrong
