45
You do not find are of an angle however an obtuse angle mesures greater than 90 degrees.
The area of the shaded region can be gotten by multiplying the area of the circle by the subtended angle of the sector.
With great difficulty because angles are degrees of measurement and not area.
The 45 degrees is an angle. To calculate an area the length and width are needed.
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!

Anything under 180 degrees

A right angle is the angle between two perpendicular lines, and, as such, has no area. You could make a right triangle from such an intersection of lines, but you need more info before you can find the area. A right angle is measured as 90 degrees or π/2 radians.
The area of the circle is(17,640)/(the number of degrees in the central angle of the sector)
Sure thing, darling! To find the area of the shaded region in a circle with a central angle of 40 degrees and a radius of 9 cm, you first calculate the area of the entire circle using the formula A = πr^2. Then, you find the fraction of the circle that the shaded region represents, which is 40/360. Multiply this fraction by the total area of the circle to get the area of the shaded region. Easy peasy lemon squeezy!

96.86 hehe ;)
if the radius of a circle is increased 100% the area is increased
A triangle with interior angles of 42, 87 and 24 degrees doesn't exist because the angles add up to 153 degrees whereas the interior angles of any triangle always add up to 180 degrees.
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!
