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
