Answer: 6.9 and 10.4
Step-by-step explanation:
The perimeter of the pentagon is 10 so you can either do 10 times 1.38 times 1/2 or do 5 times 1.38 and it equals 6.9
The perimeter of the hexagon is 12 and you follow the same steps so I did 6 times 1.73 and you get 10.4
To solve this problem, we should first recall that the circumference
is the measure of the total arc enclosing the circle. The formula for
circumference is:
Circumference = 2 π r
where r is the radius of the circle
Now since we are only looking for a fraction of the arc,
not the total arc, therefore this simply means we are finding for a portion of the
circumference. Now we use the formula:
Arc length = (θ / 360) * 2 π r
Where θ/360 represents how much of the fraction is the arc
Convert angle to degrees: θ = 1.5 rad (180° / π
rad) = (270/π)°
Therefore the arc length is:
Arc length = (270/π / 360) * 2 π (8 inches)
Arc length = 12 inches
