Ball - Geometrical FormPallo - geometrinen muotoThe calculations of the ball has a diameter of 2 units or R1 radius. This allows a comparison between the results . 1. Volumea) Formula 1 b) Formula 2 V = π * d3 V = 4 * π * r3 6 3 V = π * 23 V = 4 * π * 13 6 3 V = 4.189 V = 4.189 2. Surfacea) Formula 1A = 4 * π * r2 A = 12.566 b) Formula 2
A = p x d p = ball circumference d = diameter of the ball A = 6.283 x 2 A = 12.56(6) 3. The Ratio of Ball Surface Area and Volume12.566 / 4.189 = 3 Checking:25.132741228718345907701147066236 / 4.1887902047863909846168578443727 = 6 |
