The area of the whole circle would have been π*62
But instead of 360 degrees for the whole circle, the sector measures only 140 degrees. That is to say, the sector is 140/360 of the whole circle.
Area = π*62*140/360 = 43.9823 sq inches.
The circumference of a circle with a radius of 10 inches is about 62.83 inches.
The circumference of a circle with a diameter of 3 inches is 9.425 inches.
The circumference of a circle that has a diameter of 35 inches is 109.96 inches.
A circle with a radius of 22 inches has a circumference of 138.23 inches.
A circle with a radius of 2.6 inches has an area of 21.24 square inches.

The area of the whole circle is pi*r2 = 25*pi To go any further, you need to assume that the central angle is given in degrees. If the sector is 18.0 degrees out of a circle of 360 degrees so the sector represents 18/360 = 1/20 of the whole circle. The area of the sector, therefore, is 1/20 of the area of the whole circle = 25*pi/20 = 5*pi/4 or 1.25*pi = 12.566 sq inches.
The area of the sector of a circle with a radius of 2 inches and an arc of 60 degrees: 2.094 square inches.
The length of an arc on a circle of radius 16, with an arc angle of 60 degrees is about 16.8.The circumference of the circle is 2 pi r, or about 100.5. 60 degrees of a circle is one sixth of the circle, so the arc is one sixth of 100.5, or 16.8.
360/30*2 = 24 = circumference of the circle 24/2*pi = 3.819718634 inches = radius of the circle
The angle measure is: 90.01 degrees

Well a circle has 360 degrees so a sector of 90 degrees has an area equal to 90/360 (or 1/4) of a circle with the equivalent radius. The area of a circle is defined as PI*Radius^2 so the area of a 90 degree sector will be 1/4*PI*Radius^2. The area will be 1/4*3.14*10^2 or 78.5 in^2.

If the area of a circle is about 28 square inches the diameter of the circle is: about 6 inches (5.971).
A circle with a radius of 16 inches (32/2) has a circumference of 100.53 inches.
