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.

What is the area of the shaded sector if the circle has a radius of 3 and the central angle is 90 degrees?
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
Calculate a sector of a circle if the angle is 150 degrees and the radius is 13cm?
The area of the sector is: 221.2 cm2
How do you find the area of shaded sector of a circle?
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.
A sector of a circle has a central angle of 50 and an area of 605 cm2 Find the radius of the circle?
If the sector of a circle has a central angle of 50 and an area of 605 cm2, the radius is: 37.24 cm
What is the area of the shaded sector if the circle has a radius of 3 and the central angle is 60 degrees?
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.
How many degrees in an exterior angle?
if the radius of a circle is increased 100% the area is increased
What is the area of the shaded sector if the circle has a radius of 7 and the central angle is 45 degrees?
19.23
What is the area of the shaded sector if the circle has a radius of 3 and the central angle is 90 degrees?
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
A central angle measuring 120 degrees intercepts an arc in a circle whose radius is 6. What is the area of the sector of the circle formed by this central angle?
The area of the sector of the circle formed by the central angle is: 37.7 square units.
Calculate a sector of a circle if the angle is 150 degrees and the radius is 13cm?
The area of the sector is: 221.2 cm2
What is the radius of a circle with a cental angle of 190 degrees and the major arc area is 662.89?
It is 19.995 units.
What is the area of a sector whose central angle is ninety degrees and has a radius of ten inches?
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.
How do you find the area of shaded sector of a circle?
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.
How do you find area of shaded sector of a circle?
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.
Find area of a semi circle with angle in degree?
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!
A sector of a circle has a central angle of 50 and an area of 605 cm2 Find the radius of the circle?
If the sector of a circle has a central angle of 50 and an area of 605 cm2, the radius is: 37.24 cm
What is the area of a sector if the central angle is 45 degrees?
An eighth of the area of the circle which, since neither its radius, diameter nor circumference are known, is an unknown quantity.
