Work out the circumference of this circle take pie to be 3.142 and give your answer to 1 decimal place R=9m

C = 56.6

Step-by-step explanation:

Circumference Formula: C = 2πr

Simply plug in r into your formula

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
