Question

A school track is shown.

The track is made up of two semi-circles and a rectangle. Find the perimeter of the track. Use 3.14 for \piπ .

Answer 1

2232.36m

Step-by-step explanation:

since the perimeter of two semicircles adds up to that of one circle, the perimeter of the track would be the perimeter of the circle + the length of the rectangle.

we can find the perimeter of the circle using the formula of π × diameter, which would be:

π × diameter

= 3.14 × 74

= 232.36

now, we can add this to the given length of the rectangle:

232.36 + 1000 + 1000 = 2232.36

thus, the perimeter of the track is 2232.36m.

i hope this helps! :D
