Answer:
= (25π - 24) cm²
Step-by-step explanation:
Area of the circle = πr²
= π(5)²
= 25π cm²
Area of ΔOAB = 2(Area of ΔOCB)
AB = 6 cm
OC = 5 - 1 = 4 cm
By applying Pythagoras theorem in ΔOCB,
OB² = OC² + BC²
5² = 4² + BC²
BC² = 25 - 16
BC = √9 = 3 cm
Area of ΔOCB = 1/2 (OC) (BC)
= 1/2 (4) (3)
= 6cm^2
Area of ΔAOB = 2(6) = 12 cm²
Area of ΔAOB = Area of ΔDOE = 12 cm²
Area of shaded region = 25π - (12 + 12)
= (25π - 24) cm²
Answer:
Step-by-step explanation:
See attachment for complete question.
We start by solving for the equation of the graph (The graph shows a linear equation)
Represent pencils with x and pen with y
From the graph, we have that:
Solve for slope (m)
The equation is calculated using:
Where
Add 4 to both sides
Now, to the question.
When pencils is 15 implies that
Solving for x, we have:
i.e. Pen = 10
Ratio = x ; y
Convert to fraction
Simplify
Hence,
Answer:
46 degrees, they are equal. Hope that helped! (would appreciate being brainliest)
Step-by-step explanation:
<span><u><em>Answer:</em></u>
247,000
<u><em>Explanation:</em></u>
To round a number to the nearest thousand, we check the digit in the <u>hundreds position</u>:
1- If the digit is <u>less than 5</u>, then we round down. This means that we simply convert all digits after the thousands to zero and that's it
2- If the digit is <u>equal to or more than 5</u>, then we round up. This means that we add one to the thousands digit and then convert all digits after the thousands to zero.
In the given number 247039, the number in the hundreds position is 0. This means that we will <u>round down
</u>
Therefore, 246039 rounded to the nearest thousand would simply give 247000
Hope this helps :)</span>
