Find the area of each sector shown (the shaded section)

mihalych1998 [28]

Answer:

The area of the sector (shaded section) is 29.51 $m^{2}$ .

Step-by-step explanation:

Area of a sector = (θ ÷ 360) $\pi$ $r^{2}$

where θ is the central angle of the sector, and r is the radius of the circle.

From the diagram give, diameter of the circle is 26 m. So that;

r = $\frac{diameter}{2}$

= $\frac{26}{2}$ = 13 m

θ = 360 - (180 + 160)

= 360 - 340

= $20^{o}$

Thus,

area of the given sector = $\frac{20}{360}$ x $\frac{22}{7}$ x $(13)^{2}$

= $\frac{20}{360}$ x x $\frac{22}{7}$ x 169

= 29.5079

The area of the sector (shaded section) is 29.51 $m^{2}$ .

Please please help!! and explain!

ICE Princess25 [194]

angles in a triangle add up to 180

so x = 180 - ( 70 + 90 ) = 20

this is because the two other angles in the both of the identical triangles are 70 and 90
