A designer builds a model of a bicycle. The finished model is exactly the same shape as the original, but smaller. The scale factor is 2 () Find the ratio of the volume of the model to the volume of the original. (bFind the ratio of the surface area of the model to the surface area of the orginal ) the ratio of the width of the model to the width of the original. Wnte these ratios in the format m: n

Acircle has a circumference of 2 pi cm. which statement about the circumference and area is true? a comparison of the area and circumference is not possible since the area cannot be determined. the numerical values of the circumference and area of the circle are equal. the numerical value of the circumference is greater than the numerical value of the area. the numerical value of the circumference is less than the numerical value of the area.

Percent increase and decrease. original number: 45 new number: 18
