How to find the area of a sector whose radius is 35 cm and perimeter is 147 cm. |
|
Answer» Answer:1347.5 square units Step-by-step explanation: radius = 35 cm Perimeter of sector = 147 cm L + 2R = 147 L + 2 (35) = 147 L + 70 = 147 L = 77 cm Now we have the length of an arc and radius. So we have to use the second FORMULA to FIND the area of the given sector. Area of the sector = (1/2) x l r square units = (1/2) x 77 x 35 ==> 38.5 x 35 ==> 1347.5 square units |
