Answer:
Step-by-step explanation:
Area of the land A - Length * Width
Given
A = 1 3/4 mi²
Length L = 2 1/3 miles
Required
Width of the property
Substitute into the formula;
A = LW
W = A/L
W = 1 3/4/(2 1/3)
W = 7/4 ÷ 7/3
W = 7/4 × 3/7
W = 3/4 miles
Hence the width of the property is 3/4 miles
Answer:
see explanation
Step-by-step explanation:
The area (A) of the sector of a circle is
A = area of circle × fraction of circle
= πr² × ![\frac{\frac{\pi }{3} }{2\pi }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B%5Cpi%20%7D%7B3%7D%20%7D%7B2%5Cpi%20%7D)
diameter = 12.4 ⇒ r = 6.2, thus
A = π × 6.2² × ![\frac{1}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B6%7D)
= π × 38.44 × ![\frac{1}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B6%7D)
=
≈ 20.13 m² ( to 2 dec. places )
