Question

Look at the circle below. identify an example of radius

Answer 1

we have taht

radius is

HG

HA

HE

HD

The radius is the distance from the center of the circle to any point that lies on the circle

In this problem

point H is the center of the circle

so

the distance from H to any point on the circumference of the circle is a radius

see the attached image

All those segments are radius

Part 2

Remember that

the circumference is equal to

`C=\pi\cdot D`

so

In the table

the value of C is about 3 times the diameter

therefore

the values of flying disc are inaccurate

because

if D=23 cm the circunference must be about 69 cm, not 28 cm
