Given is quadrant of a circle… i guess

Area of a quadrant of a circle = pi r² /4 , where r is the radius of the circle formed by the given quadrant.

Pi r² / 4 = 154 cm²

=> r² = ( 154 * 4 ) * (7/22 )

=> r² = 28 * 7

=> r² = 4 * 7 * 7

=> r = 2 * 7 = 14

Perimeter of quadrant = 2r + 2pi r /4

= 28 + (2*22* 2)/4

= 28 + 22 = 50 cm

Perimeter = 50 cm

Answer 2

Answer:

50

Step-by-step explanation:

Area of a quadrant of a circle = pi r² /4 , where r is the radius of the circle formed by the given quadrant.

Pi r² / 4 = 154 cm²

=> r² = ( 154 * 4 ) * (7/22 )

=> r² = 28 * 7

=> r² = 4 * 7 * 7

=> r = 2 * 7 = 14

Perimeter of quadrant = 2r + 2pi r /4

= 28 + (2*22* 2)/4

= 28 + 22 = 50 cm

Perimeter = 50 cm
