Daisies are to be planted 6 dm apart around the circumference of a circular garden whose radius is 42 dm. How many daisies will be planted?
The circumference of a circle can be calculated using the formula C = 2πr, where r is the radius. In this case, the radius is 42 dm, so the circumference is:
C = 2π(42) = 84π ≈ 263.89 dm
If the daisies are to be planted 6 dm apart around the circumference, we can divide the circumference by the space between each daisy to find the number of daisies that will be planted:
263.89 dm / 6 dm ≈ 43.98
Since we cannot have a fraction of a daisy, we must round down to the nearest whole number. Therefore, 43 daisies will be planted around the circumference of the circular garden.
