Answer:

Step-by-step explanation:

Circumference of a circle = 2πr

Area of a circle: πr^2

Plug in:

C = 2πr

30.1 = 2(3.14)r

30.1 = 6.28r

r = 4.79 (Dividing both sides by 6.28)

Use area of the circle:

A = 3.14(4.79)^2

= 72.044474

Round to nearest whole number = 72

What is the solution to the following system of equations? x+y=5

marta [7]

Answer:

(3,2)

Step-by-step explanation:

Let's solve this via elimination method:

$\begin{cases} x+y=5\\x-y=1\end{cases}$

By subtracting equation 2 from equation one we obtain:

$\begin{cases} x+y=5\\-(x-y=1)\end{cases}\\\\0x+2y=4\\\\y=2$

Next we can use any equation either 1 or 2 to determine what x is, I'll use equation 1. Let y=2 and so:

$x+y=5\\\\x+2=5\\x=5-2\\\\x=3$

Therefore the solution for the system of equations is:

x=3 and y = 2 as an ordered pair we have (3,2)
