How many plant should my uncle need to plant around his farm of a circular shape of a radius 140 m, If the distance between plants is 50cm?

#Please guys i need your help#

the obvious answer, though probably not technically correct, is gotten by dividing the total area by the area required by each plant. That would be

π*140^2 / π*0.5^2 = (140/0.5)^2 = 78,400

The question required the number of plants around the shape and not the number of plants occupied in whole circular shape

ooops - my bad. So, divide the circumference by the plant's diameter.

If you knew enough to catch my mistake, you should know enough to figure the correct answer. What did you get?

To calculate the number of plants needed to plant around a circular farm, we first need to find the circumference of the circle.

The circumference of a circle is calculated using the formula:

Circumference = 2 * π * r

where "r" is the radius of the circle.

In this case, the radius is given as 140 m. So, substituting the value into the formula:

Circumference = 2 * π * 140

Next, we need to calculate the number of plants that can be placed along the circumference. The given distance between plants is 50 cm, which is equal to 0.5 m.

To find the number of plants, we need to divide the circumference of the farm by the distance between plants.

Number of plants = Circumference / Distance between plants

Substituting the values:

Number of plants = (2 * π * 140) / 0.5

Calculating this value will give you the number of plants needed to plant around the circular farm.
