Question

Find the diameter of a circle whose circumference is 17.6 cm.
​

Answer 1

ANSWER -:
________________________

The diameter is 5.6 cm.

________________________

EXPLANATION-:

________________________

C = Circumference

D = Diameter

R = Radius

π = 22/7 or 3.14

___________________________


Using the formulas -:

C = 2πr

D = 2r

_____________________

Solving for d =

D = c / π.

= 17.6 / π

= 17.6 / 3.14 = 5.6

__________________________

Thus 5.6 is the diameter of the circle.


___________________________

Some formulas of circle -:

Diameter of a Circle D = 2 × r

Circumference of a Circle C = 2 × π × r

Area of a Circle A = π × r^2

____________________________

Answer 2

Answer:

5.6

Step-by-step explanation:

D = c/ T.

= 17.6 / T

= 17.6 /3.14 = 5.6

Thus 5.6 is the diameter of the circle.
