The length of the arc is 18.84 u

Step-by-step explanation:

First of all we have to calculate the entire circumference

To solve this problem we need to use the circumferenc formula of a circle:

c = circumference

r = radius = 4

π = 3.14

c = 2π * r

we replace with the known values

c = 2 * 3.14 * 4

c = 25.12 u

The length of the circumference is 25.12 u

we have a partial circle of 270 ° so we have to divide it by 360 ° to know what fraction of the whole circle represents

270° / 360° = 3/4

25.12u * 3/4 = 18.84 u

The length of the arc is 18.84 u

the answer is. -82562234434584
