Step-by-step explanation:
Given that,
Sides of a triangle is 4 units, 6 units, and 7.21 units.
We need to find the area of a circle with a circumference that equals the perimeter of the triangle.
Perimeter of triangle = circumference of circle
4+6+7.21=2πr, r is the radius of circle
r = 2.73 units
Area of circle,
or
A = 24 sq units
So, the area of the circle is 24 square units.
Answer:
120 gallons would be needed
Step-by-step explanation:
You multiply both gallon amounts by the amount of people which is 60 to find how much water would be needed and you subtract them to find the difference.
(60x8)-(60x6)=
480-360= 120
Answer:
B
Step-by-step explanation:
We will first look at the end behavior of the graph
Is it down then up which means that the degree is 3 and the coeficcent is positive
this leaves B or C
We then know that the x intercepts are (-2,0) (1,0) (3,0)
The easiest way to proceed from here is just plugging in numbers into our euqation and if the end result is 0 then we got it!
looking at the B we have
-2³-2*-2²-5(-2)+6
this equals 0 which means this is our answer (this elimates C because the only difference between the two equations is the sign on the 5x)
You can also factor it and find the zeroes that way, but it's just more work
