Question

Radius of a circle is 7 cm and the angle subtended at the centre 60 .find the length of the arc.
​

Answer 1

Hey mate here is your answer.

⏺️ S =rx,

where ;S is the length of arc

⏺️ r is the radius

⏺️ x is the angle subtended at the centre.

Therefore,

➡️ your answer is 7 x pi /3.

➸ i.e 7.33

Answer 2

Answer:

7π/3 cm

Step-by-step explanation:

Use the formula, s = r×θ; where, s is the length of an arc of a circle having radius r & θ(in radian) is the angle subtended by the arc of lengh s at the center of the circle. Units of s & r are same.

Here, r = 7cm & θ = π/3 (given). [as, 60° = (60×π/180) rad = π/3 rad.]

We have to find the value of s.

So, from the above formula, we have,

s = (7×π/3) cm

= 7π/3 cm (Ans)

Hope, it'll help..!!
