Question

An arc of a circle, having measure 18 degree, has a length 22 m. Find the circumference of the circle.

Answer 1

Hi Mate!!!

Circumference of a circle = 2πr

Where r is radius.

Length of an arc = angle subtended by an arc × radius of circle.

=> Radius of circle = 22 / 18 =( 11 /9 )


=> Circumference of circle = 2π × 11 /9

= 7.67m

Have a nice time..

Answer 2

Answer:

circumference of a circle is 2πr

r is a radius

length of arc = angel of subtended by an arc × radius of a circle

22/18 = 11/9

2π×11/9 = 2×22/7 ×11/9 = 7.67meter

right answer of this question is 7.67meter
