Question

Find ciclefrence whose radius is 3.5 cm

Answer 1

Hey Mate,

Given,

Radius of the Circle = 3.5 cm

Circumference of a Circle = 2πr ( Where r is radius )

On substituting the value of the radius in the given formula, we get:-

Circumference of the circle = 2 ( 22/7 ) ( 3.5 )

Circumference of the circle = ( 44/7 ) ( 3.5 )

Circumference of the circle = 22 cm

Therefore, the circumference of a circle with radius as 3.5 cm is equal to 22 cm.

Hope it Helps!
