What is the area of sector CED when DE 15 yd?
To find the area of sector CED, we need the radius and the angle of the sector. If DE is the radius (15 yards), we would also need the angle in degrees or radians to calculate the area using the formula: Area = (θ/360) × πr² for degrees or Area = (1/2)r²θ for radians. Once the angle is provided, we can compute the area accurately. Please provide the angle for a complete calculation.
How do i find the arc length if i know the area?
Use the formula for the area of a circular sector, and solve for the angle.For a circular sector: area = radius squared times angle / 2 (Note: The angle is supposed to be expressed in radians; and in this specific problem, there is no need to convert it to degrees.) Since you know the area and the radius (according to the comments added to this question), you can solve for the angle. Once you know the angle (in radians!), the arc length is simply angle x radius.
What is the area of the shaded sector with a radius of 7?
That will depend on the length or angle of the arc which has not been given
Find the sector area of a sector with radius of 30 and an angle of 60 degrees?
apply this formula: A = t/360 r2 when t = angle at center and r = radius so A = 471.2 (rounded to 1 decimal place)
A sector of a circle has a central angle of 400 and an area of 300 cm2. Find the radius of the circle?
To find the radius of the circle, we first need to determine the radius of the sector. The area of a sector is given by the formula A = 0.5 * r^2 * θ, where A is the area, r is the radius, and θ is the central angle in radians. In this case, the central angle is 400 degrees, which is approximately 6.98 radians. Plugging in the values, we get 300 = 0.5 * r^2 * 6.98. Solving for r, we find that the radius is approximately 7.67 cm.
How do you find radius using angle of a sector?
It depends on what else is known about the sector: length of arc, area or some other measure.
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 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 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
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
A sector has an area of about 3.5 square feet and a central angle of 25°. What is the radius of the sector?
4 ft.
Area of a part of circle?
Area of a sector of a circle = (pi) x (radius)2 x (central angle of the sector / 360)
What is the area of the shaded sector if the radius is 12 and the central angle is 100?
394.7841751413609 125.6637061
What is the measure of the central angle with a sector area of 169.56 and a radius of 9?
Radius is 9 so area of complete circle (360o) is 81 x 3.14 ie 254.34. Angle of sector is therefore 360 x 169.56/254.34 which is 240o

How do you find the area of a shaded region in a circle?
(pi * radius squared) * ( sector angle / 360 )
The area of the sector formed by the 110 degree central angle is 40 What is the radius of the circle?
6.46
