Question

A circular garden has a circumference of 63 yards. Lars Is digging a straight line along a diameter of the garden at a rate of 5 yards per hour. How many hours will it take him to dig across the garden? Use 3.14 for 1 and round the diameter to the nearest whole number, if necessary. It will take Lars about hours to dig across the garden.

Answer 1

4 hours

Explanation:

f the circumference of the circular garden =63 yards

Circumference of a Circle =2πr=πd (d=diameter)

Therefore:

πd= 63

diameter of the circular garden =63/3.14=20 yards

If he digs at a rate of 5 yards per hour, the time required to dig across the garden will be:

20 yards/5 yard per hours = 4 hours

It will take him 4 hours to dig across the circular garden.
