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

answer: t=3

step-by-step explanation:

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
