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

What is the formula of the sector of the circle?
There is no specific formula for a sector of a circle. There is a formula for its angle (at the centre), its perimeter, its area.
How do you prove that A equals 25-r-5r-5 when a sector of a circle has a perimeter of 20cm and a area of A and the circle has a radius of r?
A=25-(r-5)(r-5)→10-r2(Length of Arc) + (2*radius) = Perimeter of Sector→rӨ+2r=20so Length of Arc,rӨ=20-2rArea of sector=½rӨ=rӨ(½r)Sub length of arc equation into area of sector equation gives: (20-2r)(½r)=10-r2Thus it is proved.
What is the derivation of finding the curved surface area of a cone?
first note that cone when converted to a 2d figure it is circle minus a sector cut make two equations by using area of sector and perimeter of sector (central angle/360*(pi)*r*r)and (central angle/360*2*(pi)*r)
Can you find the perimeter of a sector with the radius 6cm and the centre angle of 72 and show simple calculations THANKS?
-- The circumference of the complete circle is 2 pi R = 12 pi cm.-- The central angle of a complete circle is 360 degrees.-- A central angle of 72 degrees is 72/360 = 0.2 of the circle.-- The perimeter of the 72-degree sector is(0.2 of the whole circumference) plus (the 2 radii at the edges of the sector).-- I'm quite confident that you can handle it from this point. Don't disappoint me.
