How do you find the area of a sector with only radius given?
To find the area of a sector when only the radius is given, you'll need to know the angle of the sector in either degrees or radians. The formula for the area of a sector is ( A = \frac{1}{2} r^2 \theta ), where ( r ) is the radius and ( \theta ) is the angle in radians. If the angle is not provided, the area cannot be determined solely with the radius.
How do you find the are of the shaded sector?
To find the area of a shaded sector, you can use the formula ( A = \frac{\theta}{360} \times \pi r^2 ), where ( A ) is the area of the sector, ( \theta ) is the central angle of the sector in degrees, and ( r ) is the radius of the circle. If the angle is given in radians, the formula becomes ( A = \frac{1}{2} r^2 \theta ). Measure the radius and the angle, then apply the appropriate formula to calculate the area.
How do you find the area of a sector of a circle when you're given only the radius and not the degrees?
You cannot. The angle of the sector MUST be given, although that might be implicitly rather than explicitly.
What is the area of sector CED when DE equals 15 yd?
To find the area of sector CED, we need the radius (DE) and the angle of the sector. The area of a sector can be calculated using the formula: Area = (θ/360) × πr², where θ is the angle in degrees and r is the radius. Given that DE equals 15 yards, we would need the angle CED to calculate the area accurately. Without the angle, we cannot determine the area of sector CED.
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.
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

Find the arc length of a sector with a radius of 30 and an angle of 60 degrees?
arc length = angle/360 x r 60/360 x 30 = 5
How do you find the radius of a circle if the central angle is 36 degrees and the arc length of the sector is 2 pi cm?
The measure of the central angle divided by 360 degrees equals the arc length divided by circumference. So 36 degrees divided by 360 degrees equals 2pi cm/ 2pi*radius. 1/10=1/radius. Radius=10 cm.
How do you find the area of a shaded sector of a sector?
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.
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 you find the degrees sector of an circle?
It depends on what information you have: the radius and the area of the sector or the length of the arc.
How do you find the sector of a circle when it is 45 degrees and the radius 9?

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 approximate area of the shaded sector in the circle below 18cm?
To find the area of a shaded sector in a circle, you need the radius and the angle of the sector. Assuming the radius of the circle is 18 cm, the area of the entire circle is given by the formula (A = \pi r^2), which equals approximately (1017.88 , \text{cm}^2). If you know the angle of the sector in degrees, you can calculate the area of the sector using the formula (A_{sector} = \frac{\theta}{360} \times A_{circle}), where (\theta) is the angle of the sector. Without the angle, I cannot provide the exact area of the shaded sector.
