50 times 30 is 1500 and 9 times 8 is 72 added is 1572
A, B and c are all answers
Put the given information into the formula and solve for the variable of interest.
.. V = π*r^2*h
.. 252π = π*r^2*7
.. (252π)/(7π) = r^2
.. 36 = r^2
.. 6 = r
The radius is 6 cm. Selection D is appropriate.
_____
We would prefer that the offered selections had the appropriate cm units attached.
This is a square matrix whose entries are real and rows and columns are orthogonal unit vectors.
5x+ 10+ 15y
= 5*x+ 5*2+ 5*(3y)
= 5*(x+2+3y)
The final answer is 5(x+2+3y)~
