Answer» Sry....this solution is wrong If perimeter and radius is given,we can find the length of the arc.25=8+8+length of arcLength of the arc =25-16=9cmNow we can find the angle of the sector 9cm= angle÷360×2×22÷7×8Angle=5670÷88Area of the sector=angle÷360×22÷7×8×8 =5670×22×8×8÷88×360×7 =36cmsq. |
