Question

circumference of circle is 64 cm than find out radius and diameter​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

Radius(r) = 112/11 cm = 10.181

Diameter(d) = 224/11 cm = 20.362

Step-by-step explanation:

As we know that:-

Circumference of a circle = 2πr ...(i)

And,

Circumference = 64 cm ...(ii)

Now,

From eq. (i) and (ii) :-

2πr = 64

πr = 32

r = 32/π

r = 112/11 cm [π = 22/7]

r = 10.181

Now,

d = 2 * r = 2 * 112/11 = 224/11 cm

d = 20.362
