The formula for surface area is SA=4pi(radius)^2
This means that 4SA=4pi(2r)^2
because 2^2=4
so multiply the first ball's surface area by 4
the answer is c
Answer:
x + y = w
w > x
w > y
Step-by-step explanation:
x and y are interior angles of a triangle.
w is the exterior angle ( opposite to angles x and y ) of a triangle.
There is a formula that exterior angle of a triangle is equal to sum of two interior angles of a triangle.
So,
x + y = w
If x + y = w,
Then,
w > x
w > y
We are given with th equation <span>y = 3x2 – 12x + 12. In this respect, we expect that this is a parabola and that the vertex does not lie on (0,0). Since the power or degree is 2, it is expected that per value of y, there are two equivalent x's in the plot. You can verify it in the graph.</span>
