Question

if the circumference of the circle is 11 then find its diameter​

Answer 1

Answer:

answer is 9.44

Step-by-step explanation:

here we have to fund diameter of circle i.e. 2r

circumference = 2 {pie} r

11= 2× 3.14 × r

11- 6.28 = r

4.72 = r

as we know diameter = 2r

2× 4.72= 9.44

Answer 2

Answer:

Well the answer is 3.503

Step-by-step explanation:

We know that circumference of a circle :-

$2\pi \: r$

Where r= radius of circle

r= radius of circle Pi= 3.14

Now

$2 \times 3.14 \times r = 11$

• r = 11÷(2×3.14) = 1.75
• But we know diameter (d) is equal to twice the radius thus

So, r=2d

• r= 1.75
• 2r= d = 2× 1.75 = 3.5

Hope this helps..
