855.21 square feet. A circle with a radius 70 would be (pi)(radius squared) = (3.1416) (70) (70) = 15,393.8 square feet. With a 20 degree angle that is 20/360ths of a circle, so multiply your circle area by 20 and divide by 360 = 855.21 square feet.
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
The area of the sector is: 221.2 cm2
The area is r^2*x where r is the radius of the circle and x is the angle measured in radians. If you are still working in degrees then Area = (y/180)*r^2, where the angle is y.
If the sector of a circle has a central angle of 50 and an area of 605 cm2, the radius is: 37.24 cm
If the angle at the centre is 60° then the sector occupies 1/6 of the circle as 60/360 = 1/6. The area of a circle = πr² The area of the sector = 1/6.π3² = 9/6.π = 4.712 square units.
if the radius of a circle is increased 100% the area is increased

Find the area of the shaded sector. radius of 3 ...A+ = 7.07
The area of the sector of the circle formed by the central angle is: 37.7 square units.
The area of the sector is: 221.2 cm2
It is 19.995 units.
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.
The area is r^2*x where r is the radius of the circle and x is the angle measured in radians. If you are still working in degrees then Area = (y/180)*r^2, where the angle is y.
The area is r^2*x where r is the radius of the circle and x is the angle measured in radians. If you are still working in degrees then Area = (y/180)*r^2, where the angle is y.
The area is 0.5*pi*r2 where r is the radius. The angle is totally irrelevant since it will always by 180 degrees for a semicircle!
If the sector of a circle has a central angle of 50 and an area of 605 cm2, the radius is: 37.24 cm
An eighth of the area of the circle which, since neither its radius, diameter nor circumference are known, is an unknown quantity.
