Webb2 jan. 2024 · Multiply 2, π (pi), and the radius ( r) (the length of a line connecting the center of the circle to the edge). Alternatively, multiply π by the diameter ( d) (the length of a line cutting the circle in half). Two radii (the plural of radius) equal the diameter, so 2 r = d. π can be rounded to 3.14 (or 3.14159). Webb18 juli 2024 · Find the probability that the card is a club or a face card. Solution.
