Answer:

see explanation

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( r is the radius )

Here diameter = 12 , then radius = 12 ÷ 2 = 6 , then

A = π × 6² = 3.14 × 36 = 113.04 m²

The circumference (C) of a circle is calculated as

C = 2πr ( r is the radius )

Here C = 28.26 , then

2πr = 28.26 ( divide both sides by 2π )

r = $\frac{28.26}{2(3.14)}$ = $\frac{28.26}{6.28}$ = 4.5 in

Which system of equations would have no solution? pls helpp

Leya [2.2K]

Answer:

3x+y=8 and 3x+y=9

Step-by-step explanation:

Assume these two equations:

a1x+b1y+c1=0

a2x+b2y+c2=0

If (a1/a2) = (b1/b2) ≠ (c1/c2) than those two would have no solution.

In these case, take a look at the last option:

$3x + y = 8 \\ 3x + y = 9$

Re-write 'em as a standard form:

$3x + y - 8 = 0 \\ 3x + y - 9 = 0$

So (a1/a2) = (b1/b2) ≠ (c1/c2) is true here:

$\frac{3}{3} = \frac{1}{1} ≠ \frac{ - 8}{ - 9}$

And they do not have any collision point

Alexxx [7]

Answer:

-3,-6? im not sure what you're asking

Step-by-step explanation:

Using the coordinate plane, if you move 4 units to the left of 1 you get -3, moving it down 5 you get -6 then plug them in to the ordered pair (x,y) so (-3,-6)
