How do you find the area of the shaded sector of the circle? The radius is 10in and the sector is 45 degrees

Step2247 [10]

Given:

Radius of the circle = 10 in

Central angle of the sector = 45 degrees

To find:

The area of the sector.

Solution:

Area of a sector is

$A=\dfrac{\theta}{360^\circ}\pi r^2$

Where, $\theta$ is the central angle in degrees.

Putting r=10 and $\theta=45^\circ$ , we get

$A=\dfrac{45^\circ}{360^\circ}\pi (10)^2$

$A=\dfrac{1}{8}\pi (100)$

$A=12.5\pi$

Therefore, the area of the sector is 12.5π sq. inches.

If line b is perpendicular to line a, and linec

madam [21]

Since both lines c and b are perpendicular to line a, line c and b are parallel.

Using the two points on line b, we can count “up 5, right 5” to find the slope of line b to be 5/5 or 1.

Since line b has a slope of 1 and line c is parallel, it must also have a slope of 1.

Alison set aside $55 each month to spend on books and cd .If she spends c dollar on cds given a month she may spend b dollar on

WINSTONCH [101]

For this case we have the following equation:
c + b = 55
Where,
c: number of CDs
b: number of books
For c = 30 we have:
30 + b = 55
From here, we clear the value of b.
We have then:
b = 55-30
b = 25
Note: observe in the graph that when the value of c is 30, the value of b is 25.
Answer:
the amount Alison may spend on books in March if she spends 30 on CDs is:
b = 25
