What is the exact angle measure in radians?

495°

411π

113π

223π

114π

answer:

step-by-step explanation:

recall that in order to convert and angle given in radians into degrees, one has to use the ratio between radians and degrees. that is the fact that 180 degrees is equivalent to pi. therefore the quotient describes our conversion factor that multiplied by 405 degrees results in the angle's measure in radians:

therefore, our answer is:

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
