Answer:
120poles
Step-by-step explanation:
Given
Length of each poles of the paddock = 30
Since a square has 4 sides, the perimeter of the square shaped paddock is what we are to look for.
Perimeter of a square = 4L
L is the length of each side of the paddock
Perimeter = 4(30)
Perimeter of the square = 120
Hence he used 120poles for the paddock
Given : The Rectangular Plot has an Area of 78125 m²
Given : The Width of the Rectangular Plot is 125 m
We know that : Area of a Rectangle is given by : Length × Width
⇒ Area of the Rectangular Plot = Length × 125
⇒ Length × 125 = 78125
Answer:
<h2>R=1.0 cm</h2>
Step-by-step explanation:
V=m/d
V=8.4g/(2g/cm³)=4.2cm³
V=4 π R³/3 ; π≅3.14
R³ =3V/(4 π)=3*4.2cm³/(4*3.14)=12.6cm³/12.56 ≅ 1.0 cm³
=>R=∛(1.0 cm³) =1.0 cm
