Please help me to slove this basic polygon questions ​

(a) compute the maclaurin polynomial m2(x) for f(x) = cos x. (b) use the polynomial of part (a) to estimate cos π 12. (c) use a calculator to compute the error made using the estimate from part (b) for the value of cos π 12. remember that the error is defined to be the absolute value of the difference between the true value and the estimate.

The function models the number of accidents per 50 million miles driven as a function

52 cm radius = diameter = area = circumference = circumfer
