Question

Ming is walking around a circular track. The diameter of the track is approximately 125 meters. If Ming walks around the track 5 times how many total meters will she walk? Round your answer to the nearest whole meter.
Pd: the answer is 1963 but I don’t know the process.

Answer 1

Answer:

$1,963\ m$

Step-by-step explanation:

step 1

Find the circumference of the circular track

The circumference is given by the formula

$C=\pi D$

we have

$D=125\ m$

assume

$\pi=3.14$

substitute

$C=(3.14)(125)=392.5\ m$

step 2

If Ming walks around the track 5 times, then to find out the total meters that she will walk, multiply the circumference of the circular track by 5

$392.5(5)=1,963\ m$
