A sector has a radius of 15 centimeters and an angle of 48°. Find its arc length.

4pi or 12.57 cm

Step-by-step explanation:

Step 1 : Write the formula of arc length

Arc length = x°/360° x Circumference

Circumference = 2pir

Arc length = x°/360° x 2pir

Step 2 : Substitute the given values in the formula

x = 48°

r = 15 cm

Arc length = 48°/360° x 2pi (15)

Arc length = 4pi or 12.57 cm
