Answer:
- 127.32 yards diameter
- 12,732.4 square yards area
Step-by-step explanation:
The diameter can be found from the circumference using the relation ...
C = πd
d = C/π = (400 yd)/π ≈ 127.32 yd . . . . diameter
The area is ...
A = πr²
where the radius (r) is half the diameter.
A = π(63.662 yd)² ≈ 12,732.4 yd² . . . . area
_____
<em>Additional comment</em>
We have used a full-precision value for pi. If you use 3.14, your answers will be different. Your diameter will be about 127.4 yards; your area about 12,738.9 yd².
Answer:
-5
Step-by-step explanation:
10 minutes 15 equals -5
Answer:y=2/3x-2
Step-by-step explanation:
you need to get “Y” by itself therefore you subtract 2x on each side you will end up with -3y=-2x+6 then to get “Y” by itself you divide by -3 on both side and since there is a negative 2 on the other side a negative and a negative makes a positive and then you divide the 6 by -3 , that will give you y=2/3x-2
