58:05 1. Area of the square (a²) 2×2=4 cm² 2. Area of the circle (πr²) To find, let's cut the square into 4 triangles. Now, one diagonal = 2r To find the length of the diagonal, Let's use Pythagoras theorem (a² + b² = c²) Let diagonal be, x =2² + 2² = x² =4 + 4 = x² =8 = x² =√8 = x Diagonal= √8, Radius= √8/2 Which can be written as, √(4×2)/2 =√4×√2/2 =2×√2/2 =√2 r=√2 Now, area of the circle π×(√2)² =2π cm² 3. To find the probability, 4/2π ---------------------------- =2/π ✋🏻🙂↕️
@@Amith.p-mp9fq Won't say your answer is wrong, because it's what the question asked.. But personally I write in the simplest form (4/2π can be divided by 2, which will be 2/π) Hope you understood 🥱
Let's analyze the probability of drawing a red ball from each bag: Bag 1: * Total balls: 5 red + 10 black = 15 balls * Probability of drawing a red ball: Number of red balls / Total balls = 5/15 = 1/3 Bag 2: * Total balls: 3 red + 2 green = 5 balls * Probability of drawing a red ball: Number of red balls / Total balls = 3/5 Comparison: * Probability of drawing a red ball from Bag 1: 1/3 * Probability of drawing a red ball from Bag 2: 3/5 Conclusion: The probability of drawing a red ball is higher from Bag 2 (3/5) compared to Bag 1 (1/3).
