What is the radius of a circle with an area of 49 pi

Elenna [48]

Answer:

r = 7

Step-by-step explanation:

The area of a circle is given by the equation A = πr²

We need to manipulate the equation and solve for r

First we need to divide both sides by π and we get $\frac{A}{\pi } =r^{2}$

We then need to take the square root of both sides to get r by itself which give us $r=\sqrt{\frac{A}{\pi } }$

Now plugging in our known values we can solve for r

$r=\sqrt{\frac{49\pi }{\pi } }=\sqrt{49} =7$

Simplifying gives us the result of the radius being 7 square units

Jada added two like fractions and then wrote the answer in simplest form. The answer was 1/3. One of the addends was 3/12 . What

miss Akunina [59]

Step-by-step explanation:

The two like fractions can be set as x and y (just to use two variables).

One of them is $\frac{3}{12}$ , though, so we can set one of the variables equal to that value (I'm just going to make $y=\frac{3}{12}$ , it doesn't matter which variable you use).

We also know that adding the two variables gives us $\frac{1}{3}$ so now we can make an equation.

$x+y=\frac{1}{3} \\x+\frac{3}{12} =\frac{1}{3} \\x=\frac{1}{3} -\frac{3}{12} \\x=\frac{4}{12} -\frac{3}{12} \\x=\frac{1}{12}$

Answer:

$\frac{1}{12}$
