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 = $\frac{7}{\pi }$ ≈ 2.23 cm ( to 2 dec. places )

Store A sells a watch for $50 and offers a 5% discount. Store B sells the same watch for $60 and offers a 20% discount. The sale

marta [7]

Store A
50*5%=2.5
50-2.5=47.5
47.5+(6%*47.5)=$50.35
Store B
20%*60=12
60-12=48
48+(6%*48)=$50.88
I would but the watch from store A because it would be 53 cents cheaper.
