Answer
Explanation:
Step1: Identify relevant circle - terms
The height of the circular wheel is the diameter ($d$) of the circle, so $d = 63$ cm. The distance the wheel travels in one full - rotation is the circumference ($C$) of the circle, so $C=198$ cm.
Step2: Recall the formula for the circumference of a circle
The formula for the circumference of a circle is $C=\pi d$.
Step3: Solve for $\pi$
We can re - arrange the formula $C = \pi d$ to $\pi=\frac{C}{d}$. Substituting $C = 198$ cm and $d = 63$ cm, we get $\pi\approx\frac{198}{63}=\frac{22}{7}\approx3.14$.
Answer:
Because the wheel is circular, the height of the wheel is the diameter of the circle. The distance traveled by the wheel when it goes all the way around one time is the circumference of the circle. To estimate the value of $\pi$, divide the distance traveled by the wheel when it goes all the way around by the height of the wheel.
