Find the sector Area for both of these circles a) b)

Step 1 To find the sector area of the given circles. From the circle we have radius, r=4 θ=130∘ We know that Area of the sector is A=θ360×πr2 Hence, area of the sector is A=130360×π×4×4 A−1336×227×4×4 A=13×22×49×7=18.1587302 Therefore, sector area is A=18.1587302 Sqn units

Step 1 Radius, r=20 θ=65∘ Area of the sector is A=θ360×πr2 A=65360×227×20×20 A=65×22×2018×7=28600126 A=226.984127 Therefore , sector area is A=226.984127 units

Step 1
To find the sector area of the given circles.
From the circle we have radius,

r = 4

θ = 130^{\circ}

We know that
Area of the sector is

A = \frac{θ}{360} \times π r^{2}

Hence, area of the sector is

A = \frac{130}{360} \times π \times 4 \times 4

A - \frac{13}{36} \times \frac{22}{7} \times 4 \times 4

A = \frac{13 \times 22 \times 4}{9 \times 7} = 18.1587302

Therefore, sector area is

A = 18.1587302

Step 1
Radius,

r = 20

θ = 65^{\circ}

Area of the sector is

A = \frac{θ}{360} \times π r^{2}

A = \frac{65}{360} \times \frac{22}{7} \times 20 \times 20

A = \frac{65 \times 22 \times 20}{18 \times 7} = \frac{28600}{126}

A = 226.984127

Therefore , sector area is

A = 226.984127
