First of all, you have to manipulate the equation into the standard
form. You can simplify the 1's on both sides and you have
This means that your coefficients are
And since the solving formula is
Plugging your values yields
Surface Area of can (SA) = (2 · π · r²) + (2 · π · r · h)
296.73 = [2 · π · (4.5)²] + [2 · π · (4.5) · h]
296.73 = 40.5π + 9π · h
296.73 - 40.5π = 9π · h
(296.73 - 40.5π)/9π = h
169.5/28.27 = h
6 = h
Answer: 6 inches
Answer:
Center = (2,5)
Radius = 10
Choice A
To find this answer, first write the equation
(x-2)^2 + (y-5)^2 = 100
into
(x-2)^2 + (y-5)^2 = 10^2
Note how the second equation is in the form
(x-h)^2 + (y-k)^2 = r^2
We see that (h,k) = (2,5) is the center
and r = 10 is the radius
Answer:
5 i believe correct me if im wrong
Step-by-step explanation:
To work this problem out you would do it as if it were just a simple equation
7x-19<16 (you would first have to add 19 to both sides)
7x<35 (then you would divide by 7 to get the variable by itself)
x<5 ( you answer would then be 5)
