The head of a nail is circular, as shown. The head of this nail has a diameter of 6 millimeters. What is the approximate measurement of the area of the head of the nail in square millimeters (mm2)? Use 3.14 to approximate, do not round your answer. Show work

28.26 mm2

Step-by-step explanation:

Area = Pi r^2

diameter is 6 so radius is 3

3x3= 9

9 x 3.14 = 28.26 mm2

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
