Question

circumference of a circle is 33 find diameter

Answer 1

2r=d
2πr=33
2r=33÷π
d=10.50955

Answer 2

Hola!!
=================================

Here's your answer:

Given:

Circumference: 33

To find:

Diameter

Solution:

To find diameter it is necessary to find radius of the circle first.

Circumference = 2πr

33 = 2 × 22/7 × r

33 × 7 / 22 × 2 = r

231 / 44 = r

5.25 = r

therefore radius of the circle is 5.25.

Diameter = 2 × r

= 2 × 5.25

= 10.5

Therefore Diameter of the circle is 10.5
