Question

if the circumference of a circle is 33cm find its diameter

Answer 1

as we know that

circumference of circle = pie×d

33=22/7×d

33×7/22=d

d=10.5 cm

So diameter of circle is 10.5 cm

Answer 2

Answer:

Diameter of the circle (d) =10.5 cm

Explanation:

Let the diameter of a circle = d cm

We know that,

$\boxed{Circumference \: of \: a\: circle \:(C) \\= \pi \times d }$

Now,

C = 33cm [ given ]

=> πd = 33cm

$\implies \frac{22}{7}\times d= 33cm$

$\implies d = 33cm \times \frac{7}{22}$

$\implies d = \frac{3\times 7}{2}$

$\implies d = \frac{21}{2}$

$\implies d = 10.5 cm$

Therefore,

Diameter of the circle (d) =10.5 cm
