**Calculus**

You want the arc length of the cable. Just figure the length from the center and double it. dh/dx = 0.6√x so, the arc length from the center to the pole is just ∫[0,20] √(1+.36x) dx = 50/27 (1+.36x)^(3/2) [0,20] = 41.63 So, the cable weighs 18.2*2*41.63 = ...

**geometry**

start with the length of 16 Use a compass and from one end draw an arc with radius 8 above the first line, and from the other end draw an arc with radius 10 to intersect your first arc. Join the intersection of the arcs to the end points of the first line. There you have it then!

**Math **

For a circle of radius r, the arc length of central angle θ is given by rθ. For a circle of unit radius (i.e. radius=1), r=1, therefore the arc length equals the central angle. I hope this confirms what you were enquiring.

**Physics**

When a wheel is rotated through an angle of 35 degrees, a point on the circumference travels through an arc length of 2.5 m. When the wheel is rotated through angles of 35 rad and 35 rev, the same point travels through arc lengths of 143 m and 9.0 X 10^2 m, respectively. What ...

Using the trapezoid rule with n = 8 to approximate the arc length of the graph of y = 2x^3 - 2x + 1 from A(0,1) to B(2,13) you get (to three decimal places): A.) 6.900 B.) 13.896 C.) 14.093 D.) 13.688 E.) 13.697

How do I find the derivative for the sqrt(sin(e^(x^3)*cos(x)))??? I know this is a combination of the chain rule and product rule. Please help!

**math grade 12**

Arc length = rθ ...(1) where r is radius and θ is central angle in radians. To convert 225° to radians, multiply by (π/180) to get 225π/180=5π/4 Use formula (1) to calculate arc length, which should be in the same units as the radius.
