Answer
not sure this is right tho
Step-by-step explanation
V=3.14xr^2xh
v= 3.14x18^2 x 18
18312.48
The standard form is
(x-xo)² + (y-yo)² = r²
Where xo,yo is the center of the circumference
and r is the radius.
We find the distance between the points to determine the <span>diameter
d=sqrt ((9-2)</span>² + (4-4)²<span>) = sqrt (49) = 7
The radius of the circumference is d/2 = 7/2 = 3.5
And we can see that those points are at the same coordinate y = 4
The center is given then by , x = (9+2)/2 = 5.5
y = (4+4)/2 = 4
The equation results
(x-5.5)</span>² + (y-4)² = (3.5)²<span>
</span>
The answer is X = 6
Because 3 times 2 x is 6x ... then -1 plus 1 is 0 so it levels out and x is 6
Yes, they are equivalent
6+7-5=8. -5+10+3=8
