The 45 degrees is an angle. To calculate an area the length and width are needed.
y345y3
A = 1/2(base)(height)
90
The answer depends on what information about the circle is given: area, radius, length and angle of arc, area and angle of sector, etc. In each case, there is a different way to calculate the diameter but, since there is no information on what is known, it is not possible to answer the question.

To calculate the weight of an ISA 50x50x6mm angle, you can use the formula: Weight = Area x Length x Density. First, calculate the cross-sectional area of the angle (50x6 = 300 square mm), then convert it to square meters. Multiply the area by the length of the angle in meters and the density of the material (e.g., mild steel density is approximately 7850 kg/m^3) to determine the weight in kilograms.
There is no equivalence. An angle is a measure of rotational displacement. It is formed by two rays (or lines) and does not create an enclosed space. An area is a measure of an enclosed space.
The definition of a right angle is an angle measuring 90 degrees. You don't have to calculate anything.
The area of the sector is: 221.2 cm2
As far as my math knowledge tells me, angles have no area. angles and areas are both measurements to measure a subject. since angle is not a subject, it cannot be measured. however, angle between two lines can be measured but still, without a third line, it is impossible to find an area for it.
You cannot unless you know the angle of the plane which defines the cross section.
Area = Base times vertical height. Or, if you know trigonometry, Area = a*b*sin(C) where a and b are the lengths of two adjacent sides and C is the angle between them.
