Answer 2

Answer:

hey mate

how are uhh...??

Formulas used =

1. Circumference = 2 pie r

2. Area of Quadrant = 1/4 Pie r²

Circumference = 2 Pie r

22 = 2 × 22/7 r

r = 22 × 7 / 22 × 2

r = 7/2 or 3.5 cm

Area Of Quadrant = 1/4 Pie r²

= (1/4) × (22/7 ) × 3.5 × 3.5

= 1 × 22 × 35 × 35 / 4 × 7 × 10 ×10

= 1 × 11 × 35 / 4 × 10

= 9.625 cm²
