How long is the arc intercepted by two pi over 3 rad central angle in a circle with radius 7 feet

4.67 ft

Step-by-step explanation:

An arc is simply a portion of the circumference of a circle.

To find the length of an arc, we simply need to apply the formula:

where α = angle subtended by the arc = rads = degrees = 38.2°

r = radius of the circle = 7 ft

Hence, the length of the arc is:

The length of the arc is 4.67 ft

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
