If the area of quadrant is 4pi sqcm,then the diameter is? |
|
Answer» Step-by-step explanation: So area of the circle = 4 × (Area of quadrant) = 4 × (4π cm²) = 16π cm² Formula for area of a circle = πr² But the given area = 16π cm² A/q πr² = 16π cm² => r² = 16π/π cm² => r² = 16 cm² => r = √16cm² => r = 4cm Therefore the diameter is 2 × 4 cm = 8cm |
