Find the circumference and area of the circle to the nearest hundredth. Use 3.14 for π. Round to the nearest hundredth if necessary. 56 is the cm.

56÷2=28

Circumference=2×3.142×r

c= 2×3.142×28=175.952

hundredth =175.95cm

Area=3.142×r^2

A= 3.142×28^2=2463.328

hundredth =2463.33cm^2

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
