Answer:

Step-by-step explanation:

I think it is a ratio problem since the sides and trapezoid are congruent

It appears to be simplier than I thought. Each NEW base decreases EVERY equal step up by the SAME amount

The difference between the the bottom base and middle base is 3.5

21 - 17.5 = 3.5

The difference between the middle base and the top base is the same 3.5 so

17.5 - 3.5 = 14 is the length of the top base 3x + 2

so 3x + 2 = 14

3x = 14 - 2

3x = 12

x = 4 FINAL ANSWER

g100num [7]

Circumcerence = distance travelled in one full rotation = 2 x π x 8 = 16π

for 2 minutes and 15 seconds,
multiply 16π by 2.25 as 2 minutes is twice the distance of one rotation and 15 seconds is a quarter more

therefore answer is 36π = 113.1 inches
