What is the radius of a circle whose diameter is 3 1/2 in?

1.75 inches

Step-by-step explanation:

d=2r

Substitute 2.5 in for diameter

3.5=2r

Divide by 2 on both sides

r=1.75 inches

Hope this helps! :)

1.75

Step-by-step explanation:

radius is always half of what the diameter is

3.5 divided by 2 = 1.75

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
