Question

Find the circumference of the circle. Round your answer to the nearest hundredth.



The circumference is about
inches.

Answer 1

Circumference of a cicle in terms of radius:

Circumference = 2·π·r = 2·3.14·3 = 18.85(*)

In terms of diameter:

Circumference = π·d = 3.14·6 = 18.84(*)

In terms of area:

Circumference C = √4·π·A = √4·π·28.27 =18.85

Explanation:

Answer 2

given:

radius= 3in.

to find:

the circumference of the circle.

solution:

formula C=2πr

=2·π·3

≈18.84956in

nearest hundredth= 18.85in
