A circular garden has a circumference of 50 yards. Lars is digging a straight line along a diameter of the garden at a rate of 4 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.

8

Step-by-step explanation:

The first step is to calculate the radius

r= C/2π

= 50/2×3.142

= 50/6.284

= 7.96

Hence the diameter to the nearest whole number is 8

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

the true ones are a b and d
