What is the area of a circle if the area of its sector is 49?

The area of the circle is(17,640)/(the number of degrees in the central angle of the sector)


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.


How can you find the measure of the central angle with the sector area known?

It is found by: (sector area/entire circle area) times 360 in degrees


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


How do you get area of sector without given radius?

if given the central angle and the area of the circle, then by proportion: Given angle / sector area = 360 / Entire area, then solve for the sector area


What is the area of a sector of a circle with central angle is 18.0 and radius is 5 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.


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 sector formed by central angle of 120 degrees and a radius of 5?

A central angle of 120 is 1/3 of the total circle. Aea of a circle = pi x r2, so for this sector the area is (1/3)pi x r2 = (1/3)(3.14)(52) = 26.17


What is the area of a sector with a central angle of 50 degrees and a radius of 6?

Area of the sector is: (50/360)*pi*6 squared = 5*pi or about 15.708 rounded to 3 decimal places

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.
