Hey there!
The distance across a circle is called the diameter. Half of the diameter is the radius. To find the area of a circle, you take the radius, square it, and then multiply it by pi. Let's do it below.
8²=64
64*3.14=200.96
Therefore, the area of the rug is 200.96 ft².
I hope this helps! Have a great day.
Answer:
30% of 90
30% x 90
30/100 =3/10
3/10 x 90 = 270/10
270 = 27
90 - 27 = 63

Answer:
Step-by-step explanation:
(1) 2x - 6y = -12
(2) x + 2y = 14
There is a -6y and a +2y. Since they have opposite signs, I'll try to eliminate the y terms. (That's my choice. There is more than one way to solve these.)
Multiply eq. (2) by 3:
3x + 6y = 42
Then add the result to eq. (1) to eliminate the y terms:
2x - 6y = -12
3x + 6y = 42
------------------
5x = 30, so x = 6
Now plug the value of x into eq. (2) and solve for y:
6 + 2y = 14
2y = 8
y = 4
Why did I use eq. (2) to solve for y? Because it's less work. I could have used eq. (1) instead:
2(6) - 6y = -12
12 - 6y = -12
-6y = -24
y = 4
More than one way to solve.
