Step-by-step explanation:
radius of large sphere is R,
then volume is (4/3)*pie*R³
and
the radius of small sphere is r,
then volume is (4/3)*pie*r³
condition is,
volume of larger sphere is twice of the volume of smaller sphere.
then, (4/3)*pie*R³=2*(4/3)*pie*r³;
R³= 2r³
R=(2^⅓)*r
Answer:D
Answer:
At least two of the opposite sides must be parallel.
In the picture below, the segment AB must be parallel to the segment DC so that the figure can be called a trapezoid.
Your expression would be 9x + 3y
Coefficients with the same variables can be added together
