Hello!
The formula for the area of a sector can be written as follows:
Area =
(R)
In the above formula, “r” represents the
radius while “R” represents
the radian measure of a sector. The radius is given to us in the image above as 10 inches. However, we still need the radian measure of the two sectors. To find this measure, we can use the following conversion:
1 degree =
radians
Because the two sectors have a given measure of 72 degrees, we need to multiply both sides of the above conversion by 72:
72 degrees =
Reduce the fraction on the right side of the equation:
72 degrees =
We now have the radian measure of both sectors. Now simply insert this and any other known values into the “area of a sector” formula above:
Area =
(
)
Simplify the right side of the equation to get the following answer:
Area = 20 pi
We have now proven that
the area of one sector is equal to 20 pi.If, however, you need the combined area of the two identical sectors, simply multiply the proven area by 2 to get a total area of
40 pi.I hope this helps!
The unknown angle is <em>80°. </em>There is a <em>simple</em> formula to figure out the unknown angle. Add the angles and then subtract the sum of the two angles from 180. You would do this because the sum of interior angles of a triangle is 180°.
<em>x=180°-(angle 1 + angle 2)</em>
