<h3>What is the Length of an Arc?</h3>Any smooth curve connecting two points is called an arc. The arc length is the measurement of how long an arc is. The length of an arc is given by the formula,
where
θ is the angle, that which arc creates at the centre of the circle in degree.
Given the radius of the circle is 3m, while the angle made by the arc at the centre of the circle is 170°. Therefore,
The length of an arc = 2πr×(θ/360°) = 2π × 3 ×(170/360°) = 2.8334π m
Hence, the length of the arc m∠QPR is 2.8334π m.

The blank is -8
Step-by-step explanation:
Let us revise some rules of indices:
×
=
∵ ×
=
×
∵ All bases are equal
∴ Use the first and third rule above to find x
∵ ×
=
∴ ×
=
⇒ L.H.S
∵ ×
=
⇒ R.H.S
Equate L.H.S and R.H.S
∴ =
Equate the indices of the two sides
∴ -3 = 5 + x
- Subtract 5 from both sides
∴ -8 = x
∵ x represents the blank
∴ The blank = -8
The blank is -8
