Question

find the circumstances of if diameter is 3.2 please can you give it fast
​

Answer 1

Answer:

The circumference of a circle with radius 3.2 is 20.11(*)

Step-by-step explanation:

Circumference of a cicle in terms of radius:

Circumference = 2·π·r = 2·3.14·3.2 = 20.11(*)

In terms of diameter:

Circumference = π·d = 3.14·6.4 = 20.1(*)

In terms of area:

Circumference C = √4·π·A = √4·π·32.17 = 20.11(*)

(*) 20.11 cm exactly or limited to de precision of this calculator (13 decimal places).

Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.

hope will be helpful ☺️
