How do you find the length of a sector?
The answer depends on what information you do have: radius, arc length, central angle etc.
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
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.
A sector of a circle has a central angle of 80 degree and a radius of 5 meters. Find the area of the sector?
It is: 80/360 times 25pi = 17.453 square meters rounded to 3 decimal places
How do you find an area of a sector of a circle?
Multiply ( pi R2 ) by [ (angle included in the sector) / 360 ].
