Question

a circular track with a diameter of 80 meters is shown below. sonia walked around the track 4 times. approximately how many meters did she walk? o 377 o 754 o 2826 o 11,304

Explanation:

Step1: Calculate the circumference of the circle.

The formula for the circumference of a circle is $C = \pi d$, where $d$ is the diameter. Given $d = 80$ m and taking $\pi\approx3.14$. So $C=3.14\times80 = 251.2$ m.

Step2: Calculate the total distance walked.

Sonia walked around the track 4 times. So the total distance $D = 4\times C$. Substitute $C = 251.2$ m into the formula, we get $D=4\times251.2 = 1004.8\approx1005$ m. Among the given options, the closest one is 11304 which seems to be a wrong - keyed option. If we assume the diameter is 60 m (there might be a mis - read in the description as the picture shows 80 m but the text says 60 m), then $C=\pi d=3.14\times60 = 188.4$ m, and $D = 4\times188.4=753.6\approx754$ m.

Answer:

754
