Answer:
90.1 m
Step-by-step explanation:
The length of the shortcut is the hypotenuse of a right triangle with side lengths 30 and 85. That length can be found using the Pythagorean theorem.
PQ² = 30² +85² = 8125
PQ = √8125 ≈ 90.1
The length of the shortcut is 90.1 meters.
Answer:
14.2 is the diameter.
Step-by-step explanation:
The radius squared = 52.
What you have given is the general equation of the circle with a center at (2,-3) and a radius of sqrt(52)
You can break the 52 down.
sqrt(52) = sqrt(4 * 13) = 2 sqrt(13). Notice that 4 is a perfect square.
d = 2*radius.
d = 2(2 sqrt(13) )
d = 4 sqrt(13)
That is the diameter. You want it to the nearest 1/10
d = 14.222 but it is to the nearest 1/10
d = 14.2
Given:
In circle F, 
units.
To find:
The length of arc EG.
Solution:
It is given that, units. It means the central angle of arc EG is 122 degrees and the radius of the circle F is 16 units.
Formula for arc length is:
Where, r is the radius and 
is the central angle in degrees.
Putting 
, we get
Therefore, the length of arc EG is 34.05 units.

Answer:
<
Step-by-step explanation:
1/2 = 4/8
=> 1/8 < 4/8
=> 1/8 < 1/2
