C=2pr,  r=c/(2p)

a=pr^2, using r found above we get:

a=p(c^2/(4p^2))

a=(c^2)/(4p), since c=106.76 and we approximate pi as 3.14

a=(106.76^2)/(4*3.14)

a=11612.2176/12.56 cm^2

a≈924.54 cm^2  (to nearest one-hundredth of a square cm)

The price of a CD player was reduced from $80 to $52. What was the percent decrease in the price of the CD player? © 28% 0 35% 5
GaryK [48]

Answer:

35%

Step-by-step explanation:

Given data

Initial price= $80

Final price= $52

% decrease= initial-final/initial*100

% decrease= 80-52/80*100

% decrease= 28/80*100

% decrease=0.35*100

= 35%

Hence the decrease is 35%
