Question

find the radius and diameter of a circle puddle whose circumference is 220cm​

Answer 1

Answer:

circumference=2*22/7*r=220. 44r=220*7. r=1540/44=35. diameter =35+35=70

Answer 2

Answer:

Let the radius of the circular puddle be r

circumference of the circular puddle = 220cm

$2\pi \: r = 220cm \\ 2 \times \frac{22}{7} \times r = 220cm \\ \\ r = \frac{220 \times 7}{2 \times 22} cm \: = 35cm \\ \\ diameter \: = 2r \\ diameter = 2 \times 35 = 70cm$

✅ Hence the radius of the circular puddle is 35 and its diameter is 70 cm.
