= 0. Then using ∅=acos(0)=
= 90°
Answer:
<h2>Yes the circumference is about times greater than their diameters</h2>Step-by-step explanation:
We will approach this problem by doing a check
Say the diameter of a circle is 4 cm
Hence the radius is 3 cm
We know that the circumference is
The circumference is about 3 time bigger than the diameter
Let us try another case say the diameter is 6 cm
The radius is 3 cm
