The area of the sector formed by the 110 degree central angle is 40 units squared what is the radius
Answers
area of the circle=pi*r²
if 360° (full circle) has an area of-------------> pi*r²
110°------------------------------> 40 units²
pi*r²=40*360/110--------> pi*r²=130.91------> r²=130.91/pi-----> r²=41.69
r=6.46 units
the answer is
the radius is 6.46 units

The option B is the right answer because the vertex is (4,3)
Step-by-step explanation:
In the canonical equation of the parabola:
(X-h) ^ 2 = 4p (y-k)
The values (h, k) correspond to the coordinates (x, y) of the vertex.
In the definition of the problem it is said that the guideline of the parabola is the X axis, that is, the line Y = 0 and the focus is the point (4,6).
If the vertex were the point (4.6) the correct option would be option D
But the vertex is located at the midpoint of the segment defined by the focus points (4, 6) and the point (4, 0) that is on the parabola directrix. therefore, as the vertex is the point (4.3). the correct option is B.

Answer:
So he should go with option B
Step-by-step explanation:
The Greens will need to save to achieve his goal = $10,620
After one year if they have saved $6120.00 this means they save
6120 ÷ 12 = $510 per month
This means after 18 months they save
510 × 18 = $9,180 only. this is not enough for his goal.
so if he increases the amount of money by adding $120 from their original plan he could achieve his goal
= 510 + 120 = $630 per month
= 630 × 18 months = $11,340
So he should go with option B.
