6 inches
7 inches
12inches
24 inches

Option (a) is correct.

radius of circle whose circumference is inches is 6 inches.

Step-by-step explanation:

Given : circumference of a circle is inches

We have to find the radius of circle whose circumference is inches.

Circumference is the  distance of the outer  path of the circle.

Circumference of circle is given as  

We know circumference = inches

Substitute, we get,

inches

Solving for r,

Divide both sides by , we get,

inches

Divide both side by 2, we get,

r = 6 inches

Thus, radius of circle whose circumference is inches is 6 inches.

Option (a) is correct.

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
