<span>The formula is simply this: C = πd where C is the circumference, pi is equal to 3.1416 and d is the diameter which equal to twice the radius. We use this equation to calculate for radius. We do as follows:
</span>
C = πd
36π = πd
d = 36

d = 2r
36 = 2r

Answer:

The new width = 2 inches

Step-by-step explanation:

Original dimensions of the rectangular photo:

Length : width = 8 inches : 4 inches

Reduced dimensions of the rectangular photo:

Let

x = the new width

Length : width = 4 inches : x inches

Equate both dimensions to get the value of x

Length : width

8 inches : 4 inches = 4 inches : x inches

8 / 4 = 4 / x

Cross product

8 * x = 4 * 4

8x = 16

x = 16/8

x = 2 inches

The new width = 2 inches
