Answer: The answer is B(0,3)
Step-by-step explanation: I took the test and made sure it was correct
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
The rate is 1km/15min
It's a fraction where the denominator is 15 minutes.
To make it a unit rate, we need to make the denominator 1.
A unit rate would be 4 km / hour.
the answer is negative ten
-10
