Answer:
11 cm²
Step-by-step explanation:
The formula for the circumference of a circle = 2πr
Since 4 quadrants make a circle, their perimeter is only 1/4th that of teh circle.
Therefore the formula becomes,
(2πr)/4 = (πr)/2
∴ Perimeter of a quadrant of a circle of radius of 7 cm :
(π x 7)/ 2
→ 11 cm²
