ΔABO is a right triangle with AB⊥BO. The radius of the circle is BO. The Pythagorean theorem applies.
AO² = AB² + BO²
13² = 5² + r²
169 -25 = r²
r = √144 = 12
The radius (r) is 12.

Answer:
119
Step-by-step explanation:
Put the given values in the formula for the general term, and do the arithmetic.
an = a1 +d(n -1) . . . . . first term a1, common difference d
a14 = 2 +9(14 -1) = 119
The 14th term is 119.
Area=length times width
area=28
length=7
28=7 times width
divide both sides by 7
4=width
the width is 4 miles
and perimiter is 22mi
They would use 8 signs because one mile in this case is broken up into quarters so in a mile it would have 1/4 1/2 3/4 and 1 mile times that by two because they are placing signs for 2 miles so 4+4= 8
