How do you solve for the value of PI using the formula for circumference?

stira [4]

$\text{The circumference of a circle}\\\\C=d\pi\\\\C-circumference\\d-diameter\\\\C=d\pi\to\pi=\dfrac{C}{d}\\------------------------------\\\\\text{The area of a circle}\\\\A=\pi r^2\\\\A-area\\r-radius\\\\A=\pi r^2\to\pi=\dfrac{A}{r^2}$

$EXAMPLE:\\\\d=7\ in\to2d=7\ in\to d=3.5\ in\\C=21.98\ in\\A=38.465\ in^2\\\\\pi=\dfrac{C}{d}\to\pi=\dfrac{21.98}{7}=3.14\\\\\pi=\dfrac{A}{r^2}\to\pi=\dfrac{38.465}{3.5^2}=\dfrac{38.465}{12.25}=3.14$

Probably the last one
Use the equation for the area of a triangle 1/2(bxh)
Then multiply that number by 2 to get the area of the complete shape.

Answer:

x=1

Step-by-step explanation:

We can solve this equation using a mix of simplifying and using arithmetic on both sides:

6-4x=7x-9x+4

6-4x=-2x+4

2-4x=-2x

2=2x

1=x

x=1

First, notice that we are given the y-intercept, (0, 5), and the slope, m = 7.

We plug into slope-intercept form $y=mx+b$ to get $y=7x+5$ .
