Pupils in a school prepared a circular flower garden of diameter 28 meters. They dug holes each 4 meters apart along the circumference for planting flowers. How many holes were dug?

2 answers

the perimeter was 28π = 87.9 meters

Now you should be able to calculate the holes.

Circumference = pi*2r = 3.14 * 28 = 88.0 m.

88m * 1hole/4m = 22 Holes.
