Answer:
r=8 ft
Step-by-step explanation:
V/6π=r2
r=√v/6π
r=√1206 cubic feet/6π
r=8 ft
Yes, they are. Treat ratios like fractions, simplify them the same way. In 6/36, the GCF (Greatest Common Factor) of the numerator and the denominator is six. So, we divide both sides by six. This gives us 1/6, which is still the same fraction. (Making it proportional)
Area of circle = πr^2 = 25π (r = 5)<span>
72 degrees is 1/5 of circle
so 25</span>π / 5 = 5π
<span>
area of triangle = 1/2 bh
</span>area of triangle <span>= 1/2(5.8)(4)
</span>area of triangle <span>= 11.6
area of figure = 5</span>π - 11.6
<span>
answer
A. (</span>5π - 11.6 ) ft^2<span>
</span>
3 dilation is the answer to that
