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
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.
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 the area of the shaded area of the sector?
To find the area of the shaded sector, first determine the area of the entire circle using the formula (A = \pi r^2), where (r) is the radius of the circle. Next, find the fraction of the circle represented by the sector by dividing the central angle of the sector (in degrees) by 360 degrees or using the angle in radians divided by (2\pi). Multiply the area of the circle by this fraction to get the area of the shaded sector.

What is the measure of the central angle when the sector area is 169.56 and the radius is nine?
To find the central angle in radians for a sector, you can use the formula: ( \text{Sector Area} = \frac{1}{2} r^2 \theta ), where ( r ) is the radius and ( \theta ) is the angle in radians. Given the sector area of 169.56 and a radius of 9, we can rearrange the formula to solve for ( \theta ): [ \theta = \frac{2 \times \text{Sector Area}}{r^2} = \frac{2 \times 169.56}{9^2} = \frac{339.12}{81} \approx 4.18 \text{ radians}. ] Thus, the measure of the central angle is approximately 4.18 radians.
