Answer:
D
Step-by-step explanation:
We need the formula for arc length (in radians) to solve this problem. The formula is:
Where
s is the arc length
r is the radius of the circle
is the intercepted angle
In this diagram, we can see that is beign intercepted by the big arc with measure 20 cm. So arc length, s, is 20
Also, if we look, we see that the radius is 5 cm, so r = 5
Now, we substitute into formula and find :
This is given in radians, so is 4 radians
D is the correct answer choice.
Answer:
Step-by-step explanation:
3230 kilograms of the soil supplement are required for the entire vineyard
<h3>Further explanation</h3>
Some units that need to be recalled are as follows :
<em>1 km = 1000 m = 10³ m</em>
<em>1 km² = 1000000 m² = 10⁶ m</em>
<em>1 km² = 247 acres</em>
<em>1 kg = 1000 g</em>
Let's tackle the problem now!
A vineyard has 145 acres of Chardonnay grapes.
A particular soil supplement requires 5.50 grams for every square meter of vineyard.
<h2>Conclusion :</h2>
It required 797500/247 kg ≈ 3230 kg of the soil supplement for the entire vineyard
