Answer:
A = 50.26 sq meters
Step-by-step explanation:
we have to find the diameter first by using the circumference:
C = πd
25.12 = πd
25.12/π = d
8 = d
this means the radius is 4
A = πr²
A = π4² or 16π
A = 50.26 sq meters
Answer:
The correct answer is <em>b = 36</em>
Step-by-step explanation:
In order to find out what b is, you must find out what 9/10 is.
9/10 is 0.9. This will later be used to check our answer.
Now, solve by using cross-multiplication
b * 10 = 9 * 40.
Then use the commutative property to reorder the terms
10b = 9 * 40
Now Multiply 9 * 40 = 360
10b = 360
Now divide both sides of the equation by 10
<em>b = 36</em>
Answer:
2
Step-by-step explanation:
a = 1/2ab
~Divide 1/2a to both sides
2 = b
Best of Luck!
Answer:
B
Step-by-step explanation:
Since the inequality is < then the line separating the shaded and plain regions will be broken.
Thus graph A or B
Choose a test point in each shaded region and check validity of solution
From A choose (0, 2), then
2 < 0 +
→ 2 <
← False
From B choose (0, - 2), then
- 2 < 0 +
→ - 2 <
← True
Thus the graph representing the inequality is B
