Answer:
1. 121 π unit²
2. 143°
3. 151 unit²
Step-by-step explanation:
1.
Area of a circle is given by the formula A = πr²
where
A is the area,
r is the radius of the circle
From the given diagram, we can see that the radius is 11, hence the area will be:
The answer is units^2
2.
The unshaded secctor and the shaded sector equals the circle. We know that circle is 360°. The unshaded sector has an angle of 217°. So the shaded part will be 360 - 217 = 143°
The measure of the central angle of the shaded sector is 143°
3.
Area of a sector is given by the formula
Where
is the central angle of the sector (in our case it is 143°)
r is the radius (which is 11)
Plugging in all the info into the formula we have:
<em>rounding to the nearest whole number, it is </em>151 units^2
Answer:
20 square units
Step-by-step explanation:
The area of a parallelogram is the product of its base length and the height measured perpendicular to the base.
Here, the base is 5 units and the height is 4 units. These can be seen by counting the grid squares.
A = bh
A = (5 units)(4 units) = 20 units²
The area is 20 square units.
The center of the circle is the midpoint of the endpoints of the diameter.
Center = ((-7 + 5)/2, (3 + 1)/2) = (-2/2, 4/2) = (-1, 2)
Answer:
3n+2(n+2)=9n+12
3n+ 2n + 4 = 9n + 12
3n+ 2n +4 - 4 = 9n + 12 - 4
3n + 2n - 9n = 12 - 4
5n - 9n = 8
<u>-4n </u> = <u>8</u>
-4. -4
n. = - 2
Surveyed shoppers = 2700
Showed Interest to do business only with large well known retailers = 18% of 2700 = 486
So, Shoppers willing to do business with any size retailers = 2700 - 486 = 2214
