What is the value of r to the nearest tenth?

Mathematics
1 answer:
Tatiana [17]3 years ago
5 0

Answer:

Hence r=10.3 cms (rounded to tenth place)

Step-by-step explanation:

In Triangle KLN ,

KN = 5 Cms

LN = ½ of LM

As the Perpendicular dropped from the center to the chord bisects it.

LM = 18 cm

LN = 9 cm

Now we have to find r or KL

We apply Hypotenuse Formula in this

The formula is given as

c=\sqrt{a^2+b^2}

Where c = r

a=5

b=9

Putting them in the formula

r=\sqrt{5^2+9^2}

r=\sqrt{25+81}

r=\sqrt{106}

r=10.29

-10, -10-2·1= -12, -10-2·2=-14, -10-2·3=-16, -10-2·4= -18, -10-2·5= -20,
 -10-2·6= -22, -10-2·7 =-24, -10-2·8=-26, -10-2·9=-28

a=-10
d=-2
xn=a+d(n-1)

the first ten terms are
-10, -12, -14, -16, -18, -20, -22, -24, -26, -28
