Question

Calculate the length of the bold arc

Answer 1

Answer: length of arc is 44 cm.

Step-by-step explanation:

The formula for determining the length of an arc is expressed as

Length of arc = θ/360 × 2πr

Where

θ represents the central angle.

r represents the radius of the circle.

π is a constant whose value is 3.14

From the information given,

Radius, r = 8 cm

Angle subtended by the bold arc,θ = 315 degrees

Therefore,

Length of arc = 315/360 × 2 × 3.14 × 8

Length of arc = 44 cm rounded up the nearest whole number.
