Question

A circular garden has a circumference of 126 yards.
Lars is digging a straight line along a diameter of the garden at a rate of 20 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:

2 hours

Step-by-step explanation:

Circumference = pi × d

126 = 3.14 × d

d = 40.127388535 yards

d = 40 yards (nearest whole number)

Time = 40/20 = 2 hours

Answer 2

Step-by-step explanation:

Step 1:  Find the diameter

$C = \pi * d$

$126 = 3.14d$

$126 / 3.14 = 3.14d / 3.14$

$40.1273... = d$

40 is diameter rounded to the nearest whole number

Step 2:  Find the hours

20 yards per hour

40 / 20

2 hours

Answer:  2 hours
