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

`1,963\ m`

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`
