Find the area of the shaded portion the one who answer first will get brainliest

≈ 77 cm²

Step-by-step explanation:

The area of the shaded portion is calculated as

area of outer sector - area of inner sector

= (πR² - π r²) × ( R is the outer radius, r is the inner radius )

= (π × 14² - π × 7² ) ×

= (196π - 49π ) ÷ 6

= 147π ÷ 6

≈ 77 cm² ( nearest whole number )

Step-by-step explanation:

Circular Sector

It's the portion of a circle enclosed by two radii and an arc. The area of a sector is calculated as follows:

Where r is the radius and θ is the central angle expressed in radians. The central angle will be converted to radians:

The shaded region in the figure can be obtained by subtracting the smaller sector A2 area from the larger sector area A1:

The larger area is calculated with a radius of r1=14 cm:

The smaller area is calculated with r2=7 cm:

The shaded area is:
