Answer 1

CIRCUMFERENCE

》perimeter of a circle or an ellipse

QUESTION

The circumference of cirle whose diameter is 35 cm.

ANSWER

The circumference of the given circle is equal to 109.9 cm

FORMULA

c = 2πr

GIVEN

π = 3.14

π = 3.14d = 35 cm

since radius is half of a diameter, thus,

r = d/2

r = (35 cm)/2

r = 17.5 cm

SOLUTION

c = 2πr

c = (2)(3.14)(17.5)

c = 109.9 cm
