Question

calculate the circumference of circle A if: [The diameter is 2,456cm. Round the answer to three decimal places.

Answer 1

Step-by-step explanation:

We know that the circumference of circle = 2pie R

Note ( there is no symbol of pie in the keyboard so I write only pie.

Diameter of circle A = 2,456

We always find the circumference on its radius.

So we find the radius of circle A

When we find radius we divide the diameter by 2.

So 2456/2 = 1228

Then we find 2 pie R = 2×22/7×1228

= 22/7×614

= 13508/7

= 1929.71

So the circumference of the circle A = 1929.71
