<p>can someone post all the formulas necessary for the sat 1 math section of the test?</p>
<p>thanks</p>
<p>They are all given in the test booklet when you take the test except for:</p>
<p>Area of a sector = .5(theta)r^2
Length of a sector = (theta)r</p>
<p>Theta must be in radians.</p>
<p>Area of sector = n/100 x Pi r^2
Length of a sector = n/100 x 2 Pi r</p>
<p>For the sectors basically use Circumference and Area formulas of a circle and multiply it by n/100.</p>
<p>ok this is going to sound really stupid but is a sector just an arc of a circle?
I've never heard the terminology "sector"</p>
<p>Wait..my formulas are for an arc not sector...lol</p>
<p>"ok this is going to sound really stupid but is a sector just an arc of a circle?
I've never heard the terminology "sector""</p>
<p>Basicly the area of the sector is a "slice" of the pie or circle, and the length of the sector is the "crust" of that slice of pie.</p>
