Kiyo used wire fencing to from a border around a circlular region was 5yards, what was the total length of border, rounded to the nearest tenth of a yard

The total length of border was

Step-by-step explanation:

we know that

The length of the border would be the circumference of the circle,

The circumference of the circle is equal to

In this problem we have

-----> given problem

substitute

assume

f

step-by-step explanation:

f

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
