Answer:
area ≈ 344. 93 yard²
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
