To calculate the area of a circle we the special formula use mula Area= πx Radius & Radius 4 A = πr ² d=10cm CALCULATING THE AREA OF A CIRCLE [r=20m 4A434 A = ²√² A = 3·14×2×2 A= 12.56cm? A=56² A=3.14 SS A= 78. Sam² A = π²₁ ² A·3·14×2×2 A = 12.56=2 A+ 6.28 cm² A=X₁² -Can D) A = 3·14 × 6² = 4 A-28-26cm² If given the length of diameter divide by 2 to find the radius. Find the area of a full circle & divide by 2 for a semi-circle or divide by 4 for a quarter Circle.
