Question

A circle has a circumference of 1{,}133.541,133.541, comma, 133, point, 54 units.
What is the diameter of the circle?

Answer 1

Answer:

I don't get value of your circumference but anyway use the formula given below

Step-by-step explanation:

circumference of circle = 2πr

where r = radius of circle

hence , r = circumference /2π

now as diameter = 2 × r

and you will get answer

Answer 2

i have done this question in khan academy but the value was 1133.54

i will take the value 1133.54

you can see the steps and you can solve the question

first the formula of circumfrence is 2πr

so we will write like this

2*π*r = 1133.54

NOTE- i will take π as 3.14

2*3.14*r = 1133.54

6.28*r = 1133.54

r = 1133.54/6.28

the radius is 180.5

now we will multiply with 2 to find out the diameter

180.5*2 = 361

the diameter is 361.
