Select all the pairs that could be reasonable approximations for the diameter and circumference of a circle 19 inches and 60 inches

19 inches and 60 inches

Step-by-step explanation:

A circle is a round shaped figure with no corners or edges consisting of points such its distance from a given point (known as the centre) is always the same.

The circumference of a circle is the perimeter of the circle. That means, the circumference is the distance around the circle. It is given by the formula:

Circumference = 2πr = πd;  where r is the radius of the circle and d is the circle diameter.

a) 5 meters and 22 meters

Given that d = 5 m:

Circumference = πd = π * 5 = 15.7 m

The approximation is not close

a) 19 inches and 60 inches

Given that d = 19 inches:

Circumference = πd = π * 19 = 59.7 inches

The approximation close

c) 33 centimeters and 80 centimeters

Given that d = 33 cm:

Circumference = πd = π * 33 = 103.7 cm

The approximation is not close
