Area of shaded region = Area (sector OAPB) - Area (Triangle OAB)
Area of sector =

= 24.504 sq.cm
Area of triangle =

= 17.61 sq.cm
Area of shaded region = 24.504 - 17.61 = 6.894 <span>≈ 6.89 sq.cm
//r = radius; C = angle between radii / Sides; a,b = sides of the triangle</span>
Answer: a) t = 1.2 second
b) dL/dt = - 1.8ft/second
Step-by-step explanation: Please find the attached files for the solution
The GCF is the largest number that can go into both the terms. Since "y" isn't in both terms, it can't include y. x, however, is, so we know our GCF has x in it. What's the largest whole number that can go into 32 and 18? 2. Your GCF is <span>2x.

The area of a circle is pi × radius^2.
Diameter / 2 = radius.
4 / 2 = 2
The radius is 2. Plug this value into the area formula.
A = pi(2)^2
Area = 12.57
