1 over 4a = 2 over 3. Which of the following equals a in this equation?

dlinn [17]

Answer:

3/8

Step-by-step explanation:

The equation is given as:

$1/4*a=2/3$

We can simply the equation by getting rid of the denominators which is 4a and 3. Therefore we can multiply both sides with 3*4*a:

$(1/4*a)3*4*a=(2/3)*3*4*a$

On the left hand side 4a cancels with 4a and on the right hand side 3 cancels with 3. We are left with:

$3=2*4*a$

∴ After simplying

$a=3/8$

Express the area of a circle, a, as a function of its circumference, <br> c.

Naddika [18.5K]

Area = PI * radius^2

Circumference = 2 * PI * radius
radius = Circumference / 2 * PI

So, Area = PI * (Circumference / 2 *PI) * (Circumference / 2 *PI)
So, Area = Circumference^2 / (4*PI)
