Answer:
8.478in
Step-by-step explanation:
Length of an arc = rtheta
r is the radius of the circle = 4.5in
theta is the central angle = 0.6pi
Substitute
Length of the arc = 4.5 * 0.6pi
Length of the arc = 4.5 * 0.6 * 3.14
Length of the arc = 8.478inches
Hence the length of the arc is 8.478inches
45.61 inches
Use the pythagorean theorem.
l:9
p:16.4
l x w = A
A÷w=l
37.8÷4.4=9
2l+2w=P
18+8.4=16.4
x=4
9x-18 = x+14
9×-× = 14+18
8× = 32
X = 4
