Question

find the diameter of a circle whose circumference is 63.8 cm​

Answer 1

Circumference of a given circle is 63.8m

.•.Let the ratio of the given circle be r meter

then,

C=2πrUnits

=>C/2π

=>63.8/2×22/7

=>63.8/2 × 7/22

=>r= (31.9×0.3182)

=>r= 10.15

.•.Diameter of circle= 2r =(2×10.5) = 20.3cm

THEREFORE,

DIAMETER OF CIRCLE IS 20.3cm
