Answer:
EH = 9.4
Step-by-step explanation:
A rhombus is a quadrilateral with equal length of sides.
Given that, EF = 13 and DF = 18
⇒ DH = HF =
= 9
The property that the diagonals of a rhombus are at right angle to each other.
Thus, applying the Pythagoras theorem, we have;
=
+
=

=

169 = + 81
= 169 - 81
= 88
EH =
= 9.381
The length EH is 9.4
Answer:
Juan travel 31.4 feet farther than Fred in one rotation.
Step-by-step explanation:
In this problem we need to determine the change in linear position of Fred and Juan, whose formula is:
(Eq. 1)
Where:
- Radius, measured in feet.
- Angular arch, measured in radians.
- Change in linear position, measured in feet.
If both makes one rotation in the carousel, we obtain the change in linear position of each player:
Fred (,
)
Juan (,
)
And the difference between both travelled distances is:
Juan travel 31.4 feet farther than Fred in one rotation.
