Answer:
Given diameter of a circle = 10 cm
Radius of the circle = diameter / 2 = 10cm / 2cm = 5cm
Perimeter of a quarter circle = 2 x r x {1 + ( π/4)}
= 2 x 5 x {1 + (3.14/4)}
= 2 x 5 x {1 + 0.78}
= 2 x 5 x 1.78
= 10 x 1.78
= 17.8 cm
Now, the area of the circle = πr²
= 3.14 x 5²
= 3.14 x 25
= 78.5 cm²
∴ Perimeter of the quarter circle = 17.8 cm
∴ Area of the circle = 78.5 cm²
Hope it helps you!
