The Sector Of A Circle Has Radius Of 21 Cm And Central Angle 135o. Find Its Perimeter? |
|
Answer» PERIMETER of the sector = LENGTH of the arc + 2(RADIUS) = (135/360 * 2 * 22/7 * 21) + 2(21) = 49.5 + 42 = 91.5 cm. Perimeter of the sector = length of the arc + 2(radius) = (135/360 * 2 * 22/7 * 21) + 2(21) = 49.5 + 42 = 91.5 cm. |
