Answer:
r = 4.908
Step-by-step explanation:
V = 885
height (given in the picture) = 11.7
V = h
V = (3.14)()(h)
885 = (3.14)()(11.7)
885/3.14/11.7 =
Take the square root and you get 4.908.

Answer:
Here you go
Step-by-step explanation:
The quadratic formula helps you solve quadratic equations, and is probably one of the top five formulas in math. Then the formula will help you find the roots of a quadratic equation, i.e. the values of x where this equation is solved.
Find out the determinant
we have
2x-y=4
3x+y=1
so
D=(2)(1)-(-1)(3)
D=2+3
D=5
therefore
<h2>the answer is the second option</h2><h2>Verify</h2>
solution (1,-2)
equation 1 -------> 2(1)-(-2)=4 -------> 4=4 is true -----> is ok
equation 2 ------> 3(1)-2=1 -----> 1=1 ----> is true -----> is ok
