First find the area and arc length (which would be circumference) of the whole circle, then find 78/360 of those answers for the sector . C = 2 π r = 12π so arc length = 78/360 • 12π = 13π/5 A = π r² = 36π so area = 78/360 • 36π = 39π/5

Sectors only refer to circles you will need the central angle and the length of the radius (or diameter) of the circle so find the circumference of the circle ( C ) then perimeter = central angle/360 * C hope this helps
