Answer 1

Answer:

• 11.775 km

Step-by-step explanation:

Given

• r = 3 km

To find

• Length of 75° arc

Solution

Circumference of the circle:

• C = 2πr
• C = 2*3.14*3² = 56.52 km

The length of the 75° arc:

• 56.52*75/360 = 11.775 km

Answer 2

L=

• Ø/360(2πr)
• 75/360(2π(3))
• 75/180(6π)
• 75/30π
• 11.775km
