The area is 0.5*pi*r2 where r is the radius.
The angle is totally irrelevant since it will always by 180 degrees for a semicircle!

How to find area of a shaded area of a shaded region in a circle?
The area of the shaded region can be gotten by multiplying the area of the circle by the subtended angle of the sector.
What does a 270 degree angle look like in math terms?
It looks like 3/4 of the area of a circle and it is called a reflex angle
Area enclosed within the central angle of a circle and the circle?
Area of a sector of a circle.
How do you find an area of a sector of a circle?
Multiply ( pi R2 ) by [ (angle included in the sector) / 360 ].
How do you find the area of an arc for an example S has an arc in it how do you find the area of an s that has an arc?
A central angle can subtend (form) an arc of a circle. That has an area of 2 x pi x r x (angle A) / 360.
To find the area of a sector you multiply the area of the circle by the measure of the arc determined by the sector?
Area of sector/Area of circle = Angle of sector/360o Area of sector = (Area of circle*Angle of sector)/360o
The area of the sector formed by the 110 degree central angle is 40 What is the radius of the circle?
6.46
What is area to the nearest tenth of a 120 degree sector of a circle with radius of 8 ft?
Area of whole circle = pi*r2 = 64*pi Area of Sector = Area of Whole Circle * Angle of Sector/Angle of Whole Circle = Area of Whole Circle * 120/360 = Area of Whole Circle / 3 = 64*pi/3 = 67.0 to the nearest tenth.
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
How to find area of a shaded area of a shaded region in a circle?
The area of the shaded region can be gotten by multiplying the area of the circle by the subtended angle of the sector.
The area of the sector formed by the 110 degree central angle is 40 units what is the radius of the circle?
6.46
What does a 270 degree angle look like in math terms?
It looks like 3/4 of the area of a circle and it is called a reflex angle
What is the formula used to find the area of a sector?
area of sector = (angle at centre*area of circle)/360
How do you find the area of a shaded area?
This question is too vague to have an answer, but here is one.For the shaded area (pie wedge) of a circle, find the area of the circle and multiply by the ratio of the wedge angle to the entire circle (angle/360).For the shaded region of a triangle, find the area of the smaller triangle, if necessary using trig functions to define a known angle or length of a side.For other polygons, you may be able to divide the area into triangles separately, then sum their areas.

How do you find the area of shaded sector of a circle?
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.
