3.25 cm

6.5 cm

13 cm

13

Step-by-step explanation:

radius is half of the diameter so is the radius is 6.5cm then the diameter is 13  problem solved

13 cm

Step-by-step explanation:

Radius is half a circle & if

Radius times two that would equals diameter

6.5(2) = 13

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
