Step-by-step explanation:

the mistake was made when the value of cos 3 pi over 2 was calculated.

tan(A-B)= ?since tan=sin/cos

<u>sin</u><u>(</u><u>A-B</u><u>)</u> = <u>sinAcosB-cosAsinB</u>

cos(A-B) cosAcosB+sinAsinB

divide by cos on the RHS

tan(A-B)= <u>tanA-tanB</u>

1+tanAtanB

To answer this question you will use the formula for circumference of a circle to find how far around one revolution is.

C = pi x d
     3.14 x 32
C = 100.48 feet

Multiply the distance around one time by 4.3 to get the distance traveled in one revolution and then multiply it by 3 for the 3 minutes.

100.48 x 4.3 x 3 = 1296.19 feet
This is approximate and is closest to answer choice D.
