Answer:
22.2
Step-by-step explanation:
Hello There!
This is the sector area formula
where 0 = sector angle
and r = radius
The given sector has a measure of 50 degrees and a radius of 7.13
Knowing this information we plug it into the formula
so we can conclude that the area of the sector is 22.18178216 ft²
finally we round to the nearest tenth
and get that the answer is 22.2

Answer:
C) 19.5 square units
Step-by-step explanation:
The area from coordinates can be computed as ...
A = (1/2)|x1(y2 -y3) +x2(y3 -y1) +x3(y1 -y2)|
= (1/2)|7(10 -4) +0(4 -1) +9(1-10)| = (1/2)|7·6 +9·(-9)|
= (1/2)|-39| = 39/2 = 19.5
The area of the triangle is 19.5 square units.
