Question

If the circumference of a circle is 33 cm find its diameter take pi as 22/7

Answer 1

circumference = 33 cm
but,
circumference =2πr
=33=2*22/7*r
21/4 =r
diameter =21/4*2 is ur answer

Answer 2

circumference of a circle = 2πr
given circumference is 33 cm
hence,
$33 = 2 \times \frac{22}{7} \times r$
$r = \frac{33 \times 7}{22 \times 2}$
r=10.5
diameter= 2*r
diameter=2*10.5
diameter= 21
