Given:
Area of a sector = 64 m²
The central angle is
.
To find:
The radius or the value of r.
Solution:
Area of a sector is:

Where, r is the radius of the circle and
is the central angle of the sector in radian.
Putting
, we get




Taking square root on both sides, we get


Therefore, the value of r is
m.
Hey there! I'm happy to help!
To find the distance between two points, you find the difference between the x values, square that, find the difference between the y values, square that, add the two numbers you got, and then find the square root.
Find the difference between the x values.
-6-2=-8
Square it.
-8²=64
Find the difference between the y-values.
-5-0=-5
Square it.
-5²=25
We add the two numbers we got.
64+25=89
And we find the square root.
√89≈9.43
This method comes from the Pythagorean Theorem! If you draw a triangle that connects the two points, you can use the Pythagorean Theorem to find the distance, which is what we just did!
Have a wonderful day! :D
