The area of the full circle would be
.. A = π*(350 ft)² = 122,500π ft²
The irrigated sector is 220/360 of that area, or 235,183 ft².
Answer:
46x^2 + 73x + 15
Step-by-step explanation:
Expand both equations
Wall = (6x + 7)(8x + 5) = 48x^2 + 56x + 30x + 35 = 48x^2 + 86x + 35
Mural = (x + 4)(2x + 5) = 2x^2 + 5x + 8x + 20 = 2x^2 + 13x + 20
Minus them.
Wall - Mural =
(48x^2 + 86x + 35) - (2x^2 + 13x + 20)
(48x^2 - 2x^2) + (86x - 13x) + (35 - 20)
46x^2 + 73x + 15
Answer:
Yes
Step-by-step explanation:
Given:
Total forest area = 43,000
Old growth trees forest = 0.2%
To find:
The area of the old growth trees.
Solution:
We have,
Total forest area = 43,000
Old growth trees forest = 0.2%
Area of the old growth trees = 0.2% of 43,000
= ![\dfrac{0.2}{100}\times 43000](https://tex.z-dn.net/?f=%5Cdfrac%7B0.2%7D%7B100%7D%5Ctimes%2043000)
= ![86](https://tex.z-dn.net/?f=86)
Therefore, the area of the old growth trees is 86 acres.
