Find the area of the shaded region Gh= 13yd
Feliz [49]

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
