Answer:
3x^2 + 2x - 3y - 10
Step-by-step explanation:
7y + 2x - 10y +3x^2 - 10x
I like to put it in order starting with exponents like this
3x^2 + 2x - 10x + 7y - 10y
then combine like terms
3x^2 - 8x - 3y
that is as simplified as it gets.
First since you know the radius:3 the perimeter of a full circle would be
2pi x 3 = 6 pi. But since it's only half it would be 3 pi.
6+3+3+3pi gets you 12+3 pi
