Hell no meee plsss
the circumference of a roll of party streamers is 11 inches. the circumference decreases by 3 inches after you use the streamers to decorate for a birthday party. find the diameter of the roll after the decrease.

Diameter of the roll after the decrease = 2.54 inches

Step-by-step explanation:

Circumference of a roll of party streamers = 11 inches

Circumference of the circle is given by = 2π × radius

Now, circumference of the streamers is decreased by 3 inches

⇒ Decreased circumference of the streamers = 11 - 3 = 8 inches

To find radius of the decreased circumference streamers :

2π × radius = 8

⇒ Radius = 1.27 inches

Hence, Diameter of the roll after the decrease = 2 × 1.27

                                                                                 = 2.54 inches

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32
