Answer:
Step-by-step explanation:
The last three are irrational but I'm not sure about the first four.
(I) $ 846
(II) 157.64 cm²
Step-by-step explanation:
(I)
The area of the rectangle is;
720 * 500 = 360,000
10,000 m2 = 1 hectare
Therefore to convert the area to hectare;
360,000 / 10,000
= 36
If the cost of spraying the pesticide is $23.50 per hectare, then total cost is;
36 * 23.50
= 846
(II)
To find the area of the trapezoid;
(sum of the parallel sides * height) / 2
Height is the diameter of the circle – 21 cm
((19 + 29)*21) / 2
= 504
Then the area of the circle;
πr²
π * (21/2)²
= 346.36
The shaded area;
Area of the trapezoid – area of the circle
504 – 346.36
= 157.64
