Answer:
About 1.2 units long
Step-by-step explanation:
Circumference of a cirxle formula:
2*pi*r=C
Pi and Circumference are given so lets plug those in,
2*pi*r=7.85
6.28318530718*r=7.85
Divide both sides with 6.28318530718
r=1.24936630327
Answer: 5/10 or 1/2

Answer:
24 kilometers.
Step-by-step explanation:
The shortest path between two points is a straight segment that connects the two points.
Refer to the diagram attached. The 6-km segment and the 8-km segment are normal to each other. Together with the segment that joins the library and the house, the three segments now form a right triangle.
- The two shorter segments are the two legs, and
- The longer segment that joins the library and the house is the hypotenuse.
The length of the hypotenuse can be found with the Pythagorean Theorem.
.
The length of the round-trip will equal to the sum of the length of the three segments: .
