Question

Which statements are true about the components of a circle? Check all that apply. A. The radius is half the length of the diameter.
B. The circumferences is triple the radius.
C. The circumference is the perimeter of a circle.
D. To find the circumference, multiply by the PI
E. The diameter is triple the length of the radius.

Answer 1

The relation between diameter and radius has a relation as under -

Diameter = 2 × Radius.

So, radius is half of diameter and diameter is twice of radius.

The formula for circumference of circle = 2πr, here r represents radius.

The other formula for circumference will be = dπ, where d represents diameter.

Thus, the correct statements will be -

A. The radius is half of the length of diameter.

C. The circumference is the perimeter of circle

D. To find the circumference, multiply diameter with pi.

Answer 2

Answer: Option 'A' and 'C' are correct.

Step-by-step explanation:

Since we have given that

Components of a circle are as follows:

Radius is the shortest distance between the centre of the circle and the arc of the same circle.

Radius is half the length of the diameter.i.e. $r=\dfrac{diameter}{2}$

Diameter is the longest chord of the circle.

Circumference is the perimeter of circle i.e. $2\pi r$

Diameter is double the length of radius of circle. $d=2\times radius$

Hence, Option 'a', and 'c' are correct.
