QUESTION↷

➛ If diameter of circle is 14m,then the measure of circumference is ?

ANSWER↷

➛ Circumference of circle is 44m.

SOLUTION↷

GIVEN:

• Diameter of circle=14m

TO FIND:

• Circumference of circle

SOLUTION:

⇒ Diameter=14m

⇒ Radius=diameter/2

⇒ Radius=14/2m

⇒ Radius=7m

Hence the radius of circle is 7m.

✬ Circumference of circle=2πr

⇒ Circumference of circle=2×22/7×7

⇒ Circumference of circle=2×22

⇒ Circumference of circle=44m.

∴ Circumference of circle=44m.
