The diameter of a circle is 60cm.find the angle which an arc of length 3.14cm subtends at the circle take pie equals 3.142

s = rθ

Plugging in your numbers,

60θ = π

Oops. that's

30θ = π

To find the angle that an arc subtends at the center of a circle, we can use the formula:

θ = (s / r) * 180°

Where:
θ is the angle subtended by the arc,
s is the length of the arc, and
r is the radius of the circle.

Since we are given the diameter of the circle, we can find the radius by dividing the diameter by 2:

r = d / 2 = 60 cm / 2 = 30 cm

Now we can substitute the values into the formula:

θ = (3.14 cm / 30 cm) * 180°

θ ≈ 18.840°

Therefore, the angle that an arc of length 3.14 cm subtends at the circle is approximately 18.840 degrees.
