3x-4y=10
-20-x+2y=10 then -30+2y=x now plug this in the other equation:
3(-30+2y)-4y=10
-90+6y-4y=10
2y=100
y=50

Answer:

Circumference is 18.84 feet. Area is 28.26 square feet.

Step-by-step explanation:

Given:

Radius of the circle, $r=3\textrm{ ft}$

The value of $\pi$ is 3.14.

Now, circumference of a circle of radius $r=3$ is given as:

$Circumference=2\pi r=2\times 3.14\times 3=18.84\textrm{ ft}$

Also, area of the circle of radius $r=3$ is given as:

$Area=\pi r^{2}=3.14\times (3)^{2}=3.14\times 3\times 3=28.26\textrm{ }ft^{2}$

Therefore, the circumference of the circle is 18.84 feet and area of the circle is 28.26 square feet.
