Answer:
Radius to the diameter of a circle. Let radius of the circle be r then, diameter = 2 x radius = 2r Ratio of radius to diameter of circle ∴ Ratio of radius to diameter of circle is 1 : 2. ii. The ratio of diagonal to the length of a rectangle, having length 4 cm and breadth 3 cm. Let □ ABCD be a rectangle. In ∆ABC, ∠B = 90° AC2 = AB2 + BC2 … [Pythagoras theorem] = 42 + 32 = 16 + 9 ∴ AC2 = 25 AC = 5 … [Taking square root on both side] The ratio of diagonal to the length of a rectangle = AC/AB = 5/4 = 5 : 4 ∴ The ratio of diagonal to the length of a rectangle is 5 : 4 iii. The ratio of numbers denoting perimeter to area of a square, having side 4 cm. side of square = 4cm Perimeter of square = 4 x side = 4 x 4 = 16 cm Area of square = (side)2 = (4)2 = 16 cm2 Ratio of numbers denoting perimeter to area of square ∴ The ratio of numbers denoting perimeter to area of a square is 1 : 1.Read more on Sarthaks.com - https://www.sarthaks.com/847689/write-the-following-ratios-the-reduced-form-radius-the-diameter-circle-the-ratio-diagonal
