Question

The perimeter of the sector of the circle of radius is 4.5 cm is 25 cm then the area of sector is

Answer 1

pix8x8 = 201.1428571 sq cm. . Perimeter of the sector =25 . The arc length of the length of the sector = 25-8-8 = 9cm .

Answer 2

Step-by-step explanation:

Given: The perimeter of the sector of a circle of radius



To Find: The area of the sector.

Instruction: Find the length of the third side of the sector.

Calculation: Consider AOB

as a sector with center O



Then,

AO+AB+OB=16.4

5.2+5.2+OB=16.4

10.4+OB=16.4

OB= 16.4-10.4

OB=6cm

the area of the sector.

a=1/2×r×l

1/2×5.2×6

2.6 × 6

15.6 cm²
