...it is a fraction of a complete circle. You need to find the fraction of a circle. It is 34 / 360 (based on the angle). So the area of this sector is: 34 / 360 x pi x r^2 = 34 / 360 x 3.1416 x 5 ^ 2 = 7.42 cm(...

pie*radius^2 (if you have the diameter half it to find the radius) this will give the area of the circle (take pie as 3.142) then go: angle of sector (which sould be given) divided by 360 degrees multiply this by the area of the circle

Sectors are a bit like triangles with altitude r and base rθ, the arc length of the sector . So the area is (1/b)(base)(altitude) = (1/2)(r)(rθ) = (1/2) r^2 θ. So just plug...
