Hi there! :)
Answer:
D. 1980°
Find the sum of the measure of a 13-sided polygon using the formula:
Sum = 180(n-2), where n = number of sides
Therefore:
S = 180(13 - 2)
S = 180(11)
S = 1980°

Answer:
The length of the semicircle arc is 6π
Step-by-step explanation:
To solve this problem we need to use the circumferenc formula of a circle:
c = circumference
r = radius = 12
π = pi
c = π * d
we replace with the known values
c = π * 12
c = 12π
The length of the circumference is 12π
N
ow we divide the circumference by 2 and we will obtain the length of the arc of the semicircle
12π / 2 = 6π
The length of the semicircle arc is 6π
The chips ahoy are the better deal
Please post the question dear!
