The ratio of a model car to the size of an actual car is 1: 40. if the model is 4.5 inches long. what is the length of the full size in inches and feet?

(4.5 in)/(full size) = 1/40
full size = (4.5 in)×40 = 180 in = 15 ft

The full size of the car is 15 ft 0 in.

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 )
