1 yard = 36 inches.
8 yards = (8 x 36) = 288 inches.
Therefore, the answer to the question is "Yes.", since the quantities are equal.

Answer:
7. 2355 m
8. 1570 km
9. 157 cm
10. 40.82 m
Step-by-step explanation:
The circumference of a circle is pi * diameter or 2 * pi * radius.
If you are given the diameter, just multiply it by pi, 3.14.
If you are given the radius, then multiply the radius by 2 and then by pi, 3.14.
7. d = 750 m
circumference = pi * d = 3.14 * 750 m = 2355 m
8. d = 500 km
circumference = pi * d = 3.14 * 500 km = 1570 km
9. r = 25 cm
circumference = 2(pi)r = 2 * 3.14 * 25 cm = 157 cm
10. r = 6.5 m
circumference = 2(pi)r = 2 * 3.14 * 6.5 m = 40.82 m
Answer:
x = 6.5cm
Step-by-step explanation
Assuming that you know the abbreviation SOH CAH TOA, you can solve this easily
What we need to find is x, which is the adjacent (A) side. The other value given is the hypotenuse (H), 13cm. We will see that given A and H, we can use cosine .
cos(60) = x / 13 (remember: cos(angle) = A / H)
Multiply 13 to the other side to get x by itself,
13cos(60) = x
x = 13cos(60)
= 6.5
Hope this helps!
