A track 7m wide consists of two concentric circles. The circumference of the inner circle is 440m. Find,
1) the radius of the outer circle
2) the circumference of the outer circle.
Area of sector/Area of circle = Angle of sector/360o Area of sector = (Area of circle*Angle of sector)/360o
the ratio of the perimeter of triangle ABC to the perimeter of triangle JKL is 2:1. what is the perimeter of triangle JKL?
What is the perimeter of a square
Rectangles Perimeter Is 2L + 2W. 2(7) + 2(4) = Perimeter 14 + 8 = Perimeter Perimeter = 22
You add for perimeter...
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.
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.
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)
-- 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.
