Question

The perimeter of a sector of a circle is 37cm. If its radius is 7cm, then its arc length is

• A. 23 cm
• B. 5.29 cm
• C. 32 cm
• D. 259 cm

Answer 1

The correct option is A 23 cm

Perimeter of the Sector =37cm

Then, Radius = 7cm

Now perimeter of the sector of the circle $=$ Arc's length+ Radius+radius

37$=$ Arc's Length +7+7

Arc's Length$=$ 37-14 $=$ 23cm
