a contractor bought 8.2 ft^2 of sheet metal. she has used 3.5 ft^2 so far and has $94 worth of sheet metal remaining. the equation 8.2x-3.5x=94 represents how much sheet metal is remaining and the cost of the remaining amount. how much does sheet metal cost per square foot?

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
