If the shaded sector of the circle shown above has an area of 6 square units then what is the area of the entire circle?
The area of a sector of a circle is given by the formula ( \text{Area of sector} = \frac{\theta}{360} \times \pi r^2 ), where ( \theta ) is the angle of the sector in degrees and ( r ) is the radius of the circle. If the shaded sector has an area of 6 square units, we need the angle to determine the entire area of the circle. However, assuming this sector represents a certain fraction of the circle, the area of the entire circle can be found using the formula ( \text{Area of circle} = \frac{6 \times 360}{\theta} ). If the angle is known, you can calculate the total area accordingly.

Find the area of the shaded sector when the radius is 12 and the not shaded is 100?
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.
What is the shaded sector of the if radius is 3 and the degrees is 90?
It depends whether the UNSHOWN figure has the shaded sector as the sector which includes the 90° angle, or the one which excludes it. Assuming that it is the sector including the 90° angle, ie the question should have been written: What is the area of a sector of a circle with a radius of 3 units when the angle of the sector is 90°? It is a fraction of the whole area of the circle. The fraction is 90°/360° (as there are 360° in a full turn and only 90° are required) = 1/4 Area circle = π × radius² = π × (3 units)² = 9π square units → area 90° sector = ¼ × area circle = ¼ × 9π square units = 9π/4 square units ≈ 7.1 square units
What is the area of the shaded region of a circle if the diameter is 18 centimeters and the area shaded is 270?
To find the area of the shaded region, you first need to calculate the area of the entire circle. The radius of the circle is half the diameter, so it is 9 centimeters. The area of the circle can be calculated using the formula ( A = \pi r^2 ), which gives approximately ( 254.47 ) square centimeters. Since the shaded area is given as 270 square centimeters, this indicates that the shaded region exceeds the area of the circle, suggesting a possible error in the given dimensions or a misunderstanding of the problem.

What is the area of the shaded region of a circle if the diameter is 18 centimeters and the area shaded is 270 degrees?
To find the area of the shaded region of the circle, first calculate the area of the entire circle using the formula ( A = \pi r^2 ). The radius ( r ) is half the diameter, so ( r = 9 ) cm. Thus, the area of the circle is ( A = \pi (9^2) = 81\pi ) square centimeters. Since the shaded region is 270 degrees, which is ( \frac{3}{4} ) of the circle, the area of the shaded region is ( \frac{3}{4} \times 81\pi = 60.75\pi ) square centimeters, approximately 191.1 square centimeters.
Find the area of the shaded sector when the radius is 12 and the not shaded is 100?
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.
