Answer:
The length AB is 23.4in
Step-by-step explanation:
N/B please see the attached detailed diagram for your reference and better understanding
This problem bothers on the mensuration of flat shapes.
The width AB is the chord of the wheel
The radius of the whee r= 25/2= 12.5in
The depth of the wheel in the puddle is 8.1in
Let b be the distance from the surface AB to the diameter
b= 12.5-8.1 = 4.4in
Applying the formula
Chord Length = 2 *√(r²-b²)
=2*√(12.5²-4.4²)
= 2*√(156.25-19.36)
=2*√(136.89
=2*11.7
=23.4in
