The area of the sector is a fraction of the area of the whole disk. So, we need to find the area of the whole disk and then multiply by the ratio of the sector size to the disk. The ratio is 2/3 pi out of a disk that is 2 pi all around (like any circle). Twos cancel, "pi"s cancel, so the sector is 1/3 of the disk. The disk's area is pi times (the radius squared). Pi times four. Well, to avoid using Irrational Numbers, the disk's area is 4 pi. The sector is 1/3 of 4 pi square feet, which is 4/3 pi square feet.
Yes. Besides the included angle, arc length is also dependant on the radius. Arc length = (Pi/180) x radius x included angle in degrees.
Radius is half the diameter, so 25 yards.
It is 10/18 = 0.55... radians.
measure from the middle out to one side
The volume of a cylinder is represented by this formula:r2Ï€hwhere r = radius of circular baseand h = height of cylinder
The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.
Radius is a sensible measure to use with a circular (or spherical) shape. England is neither.

I got 1.3
-- Circumference of the circle = (pi) x (radius) -- length of the intercepted arc/circumference = degree measure of the central angle/360 degrees
You also need the measure of the central angle because arc length/2pi*r=measure of central angle/360.
you do the area of the base (circle - pi*radius squared) times the height (measure the tubular face).
That depends on the questions which have not been given but in general circular measurements are:- Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius2
40.7 in : presumably inches, is a measure of distance. It has nothing whatsoever to do with a circular shape and so has no equivalent radius - or raduis, even.
Yes. Besides the included angle, arc length is also dependant on the radius. Arc length = (Pi/180) x radius x included angle in degrees.
The radius of a cylinder is half the thickness of its circular cross section.
It is: 36/18pi times 360 = about 229 degrees
