The circumference of a circle is 14 cm. Find the radius of this circle

Sagot :

2.23 should be the radius

Answer:

r ≈ 2.23 cm

Step-by-step explanation:

the circumference (C) of a circle is calculated as

C = 2πr ( r is the radius )

given C = 14 , then

2πr = 14 ( divide both sides by 2 )

πr = 7 ( divide both sides by π )

r = [tex]\frac{7}{\pi }[/tex] ≈ 2.23 cm ( to 2 dec. places )
