Answer:
44 in
Step-by-step explanation:
In the picture it shows that the diameter of the circle is 14in. Using the formula we know that the diameter (14) times pi equals the circumference.

Answer:
L = ∫₀²ᵖⁱ √((1 − sin t)² + (1 − cos t)²) dt
Step-by-step explanation:
Arc length of a parametric curve is:
L = ∫ₐᵇ √((dx/dt)² + (dy/dt)²) dt
x = t + cos t, dx/dt = 1 − sin t
y = t − sin t, dy/dt = 1 − cos t
L = ∫₀²ᵖⁱ √((1 − sin t)² + (1 − cos t)²) dt
Or, if you wish to simplify:
L = ∫₀²ᵖⁱ √(1 − 2 sin t + sin²t + 1 − 2 cos t + cos²t) dt
L = ∫₀²ᵖⁱ √(3 − 2 sin t − 2 cos t) dt
Two factors could be .22 and 1. .22 times 1= .22

Answer: h = -17.5
Step-by-step explanation:
Move the like-terms together on the right side and the other to the left side.
1.6h - 4h = 72 - 30
Subtract both sides:
1.6h - 4h = -2.4h
72 - 30 = 42
-2.4h = 42
Divide -2.4 by both sides
-2.4h/-2.4 = 42/-2.4
h = -17.5
