Horace measured a circular lid and found d, the diameter, was 8 inches and C, the circumference, was 25 inches.

A/C ≅ 2

Step-by-step explanation:

diameter of circle d = 8 in

Circumference of the circle C= 25 in

Let us assume we have to find the area of the circular lid  A =

⇒ A=

Therefore ratio of area to circumference A/C = 50.24/25 = 2.0096≅2

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":
