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.
The area of the shaded region can be gotten by multiplying the area of the circle by the subtended angle of the sector.
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
To find the area of the shaded sector, we first need to determine the area of the entire circle with a radius of 12, which is calculated using the formula (A = \pi r^2). Thus, the area of the entire circle is (A = \pi (12^2) = 144\pi). If the not shaded area is 100, the area of the shaded sector is then (144\pi - 100). Therefore, the area of the shaded sector is approximately (144\pi - 100) square units.
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.
(pi * radius squared) * ( sector angle / 360 )
To find the area of the shaded sector, we need to determine the total area represented by the shaded and non-shaded parts. If the shaded sector is 155 and the rest is 4.3, the total area is 155 + 4.3 = 159.3. The area of the shaded sector is already given as 155, so rounding it to the hundredth gives us 155.00.
find the area of the shaded sector 12cm and 24°
area of whole circle = pi * radius squared = 3.14159 * 36 = 113.1area of sector = 113.1 * ( 10 / 360 ) = 3.14159 sq units
Area of sector/Area of circle = Angle of sector/360o Area of sector = (Area of circle*Angle of sector)/360o
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.
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.
To find the area of a shaded sector, you need the radius and the angle of the sector. If you have a circle with a radius of 7 and a central angle of 45 degrees, the area of the sector can be calculated using the formula: [ \text{Area} = \frac{\theta}{360} \times \pi r^2 ] Substituting the values, we get: [ \text{Area} = \frac{45}{360} \times \pi \times 7^2 = \frac{1}{8} \times \pi \times 49 \approx 19.63 ] So, the area of the shaded sector is approximately 19.63 square units.
