<em>Greetings from Brasil...</em>
Here we will apply rule of 3...
This formula, A = πR², its for the whole circle, that is, 360° (2π)
We want the area of only a part, that is, a circular sector whose angle π/6
sector area
2π ----- πR²
π/6 ----- X
2πX = (π/6).πR²
2πX = π²R²/6
X = π²R²/12π
<h3>X = πR²/12</h3>
If Ronisha multiply the area by 1/12 she will get the area of sector with angle of π/6
Answer:Ages 11 and 15.
Step-by-step explanation:
Although, I cannot answer this properly due to grammatical errors, I think its safe to say you were referring to the younger brother, whom of which would be 11.
Answer:
180
Step-by-step explanation:
Let x be the first integer.
Let y be the 2nd integer.
Given info from the question,
x = 5% x y
x = 0.05y - equation 1
x + y = 63 - equation 2
Lets now substitute equation 1 into equation 2.
0.05y + y = 63
1.05y = 63
y = 63 / 1.05
= 60
Now we substitute y into equation 1.
x = 0.05(60)
= 3
Now since we know both x and y,
we can find the product of them.
xy = 60 * 3 = 180
