Question

A circular garden has a circumference of 138 yards. Lars is digging a straight line along a diameter of the garden at a rate of 11 yards per hour. How many hours will it take him to dig across the garden? Use 3.14 for π and round the diameter to the nearest whole number, if necessary

Answer 1

Answer:

• 4 hours

Step-by-step explanation:

Circumference formula:

• C = πd

Use the given value and find the diameter:

• 138 = 3.14d
• r = 138/3.14
• r = 43.94 ≈ 44 yards

Time required to dig across the garden:

• 44/11 = 4 hours
