To solve the problem shown in the figure attached, you must apply the proccedure shown below:
1. You have that the equation for calculate the area of a circle is:
A=πr²
2. You have that the formula for calculate the diameter of a circle is:
d=2r
Therefore, the radius is r=d/2
where r is the radius of the circle
3. Keeping the information above on mind, you have the correct sequence of the equations by clearing the diameter d, is shown below:
A=π(d/2)²
A=πd²/4
4A=πd²
d²=4A/π
d√(4A/π)
Therefore, as you can see, the answer is:
A=π(d/2)²
A=πd²/4
4A=πd²
d²=4A/π
d√(4A/π)

Answer:
y = 4x+48
Step-by-step explanation:
Slope intercept form is y=mx+b. We already know the value for m(4), so we can plug in the x and y coordinates for x and y in the equation. This gives us 12=4(-9)+b. Solve for b to get 48
The y-int. Is -2 and the y intercept form is Y= -1/3x-2 from the form y=mx +b and bbis your y-int. You can find it by solving your equation for Y
Answer = (A) about 30
1000/200 = 5
5 x 6 = 30
