**Task definition**

Find a post with a bus stop on it. Find the area of cross section of the post under the bus schedule. The answer you get now multiply it by 0.47211 and you will get the world ranking in the UK.

**Solution move**

1.  Find a post
2.  Measure the area of cross section of the post
3.  Multiply it

**Mathematical calculation step**

circ=52cm  
circ=2x3.14xr  
2x3.14xr=52cm  
r=52\\2x3.14=8.28cm  
Area of the circle>  
3.14 x r'2  
3.14 x d'2\\4  
d=2 x r = 8.28 x 2=16.56cm  
3.14 x r'2= 3.14 x 68.5584 = 215.27336 cm2  
3.14 x d'2\\4= 3.14 x 274.2336\\4= 215.273376 cm2

Hint 1

Measure the circumference under the sign.

Hint 2

Find the radius and the diameter.

Hint 3

Radius r = d / 2 Diameter = 2 × Radius.

**Connection to the study**

Bus stop is a traffic object.
