Question

If the circumference of a circle is 880 cm, it's diameter will be

Answer 1

Answer:

radius of the circle is 880×7/2×22

i.e. 20

then the diameter is 20+20

i.e. 40

Answer 2

given

circumfrence of circle = 880 cm

circumfrence formula = 2πr

2πr = 880

r = 880 / 2π

r = 880 / 2(22/7)

r = 880 . 7 / 2.22

r = 6160 / 44

r = 140

as diameter is double of radius then

diameter = 140 . 2

= 280 cm
