V=1/3πr² Solving for r²

1 answer:

6 0

Multiply both sides of the equation by 3.
$3V= \pi r^{2}$

Divide both sides of the equation by π.
$\frac{3V}{ \pi } = r^{2}$

Solved!!!! :-)

Sum of complementary angles = 90
so
5x + 35 = 90
5x = 90 -35
5x = 55
x = 11

Answer:

The value of n is 30.25.

Step-by-step explanation:

The given expression is

$x^2+11x+n$ ....(1)

The perfect square trinomial are defined as

$(x+y)^2=x^2+2xy+y^2$ .....(2)

On comparing (1) and (2), we get

$2y=11$

$y=\frac{11}{2}$

The given expression is perfect square trinomial if

$n=y^2$

$n=(\frac{11}{2})^2$

$n=\frac{121}{4}$

$n=30.25$

Therefore the value of n is 30.25.

Y=5x-2. Substitute into the second
-3x+6(5x-2)=-12
-3x+30x-12=-12
The -12 cancel
27x=0
x=0
y=-2
check in the second equation
0+6(-2)=-12
(0,-2)
