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.
