Answer:
1/9
Step-by-step explanation:
Separate the fraction (1/9) from the variable x:
y = (1/9)x.
1/9 is the constant of proportionality.
Point Q is -6 from point R
Point R is 7 from point T
Point T is -3 from point S
Area = 1/2(6+9)(7)
Area = 1/2 (15)(7)
Area = 52.5 square units
We know that
area of a circle=pi*r²-------> r=√[area/pi]
for area=5000 ft²
r=√[5000/pi]----> r=39.90 ft
39.90*2-----> 79.8 ft of diameter
79.8 ft is > 40 ft
therefore
the answer is
<span>No, he forgot to multiply the radius by 2.</span>
