Respuesta :
we know that
length of a sector=[∅]*r--------> when ∅ is in radians
so
∅=length of a sector/r
for r=7 ft
length of a sector=4 ft
∅=4/7-----> 0.57 radians
the answer part 1) is 0.57 radians
part 2)
area of a sector=(∅/2)*r²--------> when ∅ is in radians
area of a sector=(4/7/2)*7²-----> (4/14)*49----> 14 ft²
the answer Part 2) is 14 ft²

Answer:
In a circle with a radius of 7 feet, the radian measure of the central angle subtended by an arc with a length of 4 feet is 0.57 . The area of the sector formed by the arc is 13.97 square feet. Assume π = 3.14, and round your answers to the nearest hundredth.
