Question

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

Answer 1

A/C ≅ 2

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 =
`(\pi)/(4)d^2`

⇒ A=
`(\pi)/(4)*8^2= 50.24 in^2`

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