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 . the area of the sector formed by the arc is square feet. assume π = 3.14, and round your answers to the nearest hundredth.

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
