Circumference of circle = 2πr
308 cm = 2πr
308 / 2 cm= πr
154 cm = 22r / 7 [ π = 22 / 7 ]
154 × 7 / 22 cm = r
7 × 7 cm = r
49 cm = r or radius
Then,
Area of circular sheet = πr²
Area of circular sheet = 22 / 7 × 49 × 49 cm²
Area of circular sheet = 22 × 7 × 49 cm²
Area of circular sheet = 7546 cm²
308 cm = 2πr
308 / 2 cm= πr
154 cm = 22r / 7 [ π = 22 / 7 ]
154 × 7 / 22 cm = r
7 × 7 cm = r
49 cm = r or radius
Then,
Area of circular sheet = πr²
Area of circular sheet = 22 / 7 × 49 × 49 cm²
Area of circular sheet = 22 × 7 × 49 cm²
Area of circular sheet = 7546 cm²
