What is the perimeter of a sector?
The formula for the perimeter of the sector of a circle is given below : Perimeter of sector = radius + radius + arc length. Perimeter of sector = 2 radius + arc length.
What is sector area formula?
The formula for sector area is simple – multiply the central angle by the radius squared, and divide by 2: Sector Area = r² * α / 2.
What is the central angle of 90 degrees?
A degree is a measurement of angle. One full rotation around the circle is equal to 360 degrees, so one degree is 1360 of a circle. An angle measured in degrees should always include the unit “degrees” after the number, or include the degree symbol ∘. For example, 90 degrees=90∘.

What’s the largest square inside a circle?
The maximum square that fits into a circle is the square whose diagonal is also the circle’s diameter. The length of a square’s diagonal, thanks to Pythagoras, is the side’s length multiplied by the square root of two. Set this equal to the circle’s diameter and you have the mathematical relationship you need.
