Answer:
2
Step-by-step explanation:
3/8+3/4+7/8
=3/8+6/8+7/8
=16/8
=2
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 ∅<span> is in radians
</span>area of a sector=(4/7/2)*7²-----> (4/14)*49----> 14 ft²
the answer Part 2) is 14 ft²
D because both sides have a length of 5
1. y=1.04+61.92
i think correct answer on the second slide is A
