A circular garden has a circumference of 88 yards. Lars is digging a straight line along a diameter of the garden at a rate of 7
ankoles [38]

Answer:

It will take 4 hours to dig in the garden

Step-by-step explanation:

First we have to calculate the diameter, for this we will use the formula to calculate the circumference of a circle and we will clear the diameter

d = diameter

π = 3.14

c = circumference

c = π * d

d = c / π

d = 88yd / 3.14

d = 28.025yd

round to the nearest whole number

28.025 = 28

d = 28yd

To know how many hours it takes, we divide the diameter by the speed

t = time

v = velocity

t = d / v

t = (28yd) / (7yd/h)

t = 4h

It will take 4 hours to dig in the garden

Divide it into 1 rectangle and 3 triangles.

Rectangle : 3 x 8 = 24

Triangle 1: 1/2 x 8 x 2 = 8

Triangle 2: 1/2 x 4x3 = 6

Triangle 3: 1/2 x 4x3= 6

Total area = 24 + 8 + 6 + 6 = 44 square units.
