Answer:
area ≈ 344. 93 yard²
Step-by-step explanation:
The question you are asking is a circle with shaded portion and a portion not shaded . The radius of the circle is given as 13 yards . H is the center of the circle and unshaded part of the the sector has an angle of 126°.
The area of a sector = ∅/360 × πr²
The other angle of the shaded portion is unknown . To find the angle we subtract 126° from 360°(complete angle).
360 - 126 = 234°
area of a sector = ∅/360 × πr²
where
∅ = 234°
r = 13 yards
area = 234/360 × π × 13²
area = 234/360 × π × 169
area = 39546π/360
area = 109.85π
area = 109.85 × 3.14
area of the shaded part = 344.929 yard²
nearest hundred will be
area ≈ 344. 93 yard²
To solve for a variable, you need to get it (x) by itself.
2x² - 4x + 5 = 6 Subtract 6 from both sides
2x² - 4x - 1 = 0 Plug this into the Quadratic Formula
a = 2 , b = -4 , c = -1
x =

Answer & Step-by-step explanation:
2a - b : 2a + b = 1 : 2
2a - b = 1
- Elimination
2a + b = 2
-b - (b) = -1
-2b = -1
b = 0.5
---------------------------------------------------------------------------------
2a + b = 2 Substitution
2a + 0.5 = 2
2a = 1.5
a = 0.75
--------------------------------------------------------------------------------------
a:b
0.75 : 0.5
or
3/4 : 1/2
Hope this helps!!!
