Question

Jason designed an arch made of wrought iron for the top of a mall entrance. The 11 segments between the two concentric circles are each 1.25 m long. Find the total length of wrought iron used to make the structure. Round the answer to the nearest meter.

Answer 1

I like this question.

Answer 2

diameter of outer circle is 15 m right?

Answer 3

total length = (11*1.25) + piR1 + piR2
R1 = radius of outer circle
R2 = radius inner circle

Answer 4

So that's the answer? @dumbcow

Answer 5

@eleven17 I'm glad you do.

Answer 6

yes just plug in the numbers for the 2 radii
i couldnt tell from the image

Answer 7

ok thanks :)
