The Circle Will Be Dilated By A Scale Factor Of 6 Radius Is 9 In What Is The Value For N If The Expression Nt Represents The Circumference Of The Circles In Inc class=

Sagot :

Answer:

3

Step-by-step explanation:

to dilate is to divide or to make smaller.

when dilating by a factor of 6, take one of the measurements given which is 9 and divide it by 6.

9/6 = 3/2 = 1.5

1.5 is the new radius

the circumference formula is 2*pi*r or pi*d where 'd' is the diameter. without evaluating with pi, this is what you get:

2*pi*r

2*pi*1.5

3*pi

now 'n' equals 3
