Question

find the following ratios
1. the ratio of radius to circumference of the circle
2. the ratio of circumference of circle with radius R to its area
3. the ratio of diagonal of square of its side ,if the length of side is 7 cm​

Answer 1

Answer:

• ∴ The ratio of circumference of circle with radius r to its area is 2 : r.

• ∴ The ratio of diagonal of a square to its side is √2 : 1.

• ∴ Ratio of numbers denoting perimeter to the area of rectangle is 34 : 35.

Step-by-step explanation:

Hi Sonali sis

how are you

Answer 2

Answer:

i. Let the radius of circle be r. then, its circumference = 2πr Ratio of radius to circumference of the circle .

- The ratio of radius to circumference of the circle is 1 : 2π.

ii. Let the radius of the circle is r. ∴ circumference = 2πr and area = πr2

- Ratio of circumference to the area of circle

∴ The ratio of circumference of circle with radius r to its area is 2 : r.

iii. Length of side of square = 7 cm

∴ Diagonal of square = √2 x side = √2 x 7 = 7 √2 cm

Ratio of diagonal of a square to its side
