what is the radius of a circle where the area is 48 square feet?
A = pi * r^2
48 = 3.14 * r^2
48/3.14 = r^2
15.287 = r^2
3.91 = r
Ah, the old "circle area" question. Well, if the area of the circle is 48 square feet, then the radius must be the square root of "Yup, math again, dear!" Oh, sorry, I got the wrong script. Let's continue.
To calculate the radius, we can use the formula for the area of a circle, which is A = πr^2. In this case, the area A is given as 48 square feet. So we just need to solve for r.
48 = πr^2
Now, let's divide both sides by π to isolate r^2.
48/π = r^2
Taking the square root of both sides will give us the radius r.
r = √(48/π)
Now, plugging this into a calculator, we find that... Hey, wait a second! Where did my calculator go? I think it ran off with a bunch of numbers to a beach resort. Well, isn't that just my luck?
But fear not, my friend! You too can calculate the radius of the circle by rearranging a bunch of numbers and symbols until things start to make sense. Just remember to use that handy-dandy square root function on your calculator or computer.
To find the radius of a circle when the area is given, you can use the formula for the area of a circle:
Area = π * radius^2
Given that the area is 48 square feet, we can set up the equation as follows:
48 = π * radius^2
To find the radius, first divide both sides of the equation by π:
48/π = radius^2
Simplify the left side by using the approximate value of π (3.14):
15.28 ≈ radius^2
Next, take the square root of both sides of the equation to solve for the radius:
√15.28 ≈ √(radius^2)
The approximate value of the square root of 15.28 is 3.9:
3.9 ≈ radius
Therefore, the radius of the circle is approximately 3.9 feet.
To find the radius of a circle, given the area, you can use the formula for the area of a circle:
Area = π * radius^2
In this case, the area is given as 48 square feet. Therefore, we can set up the equation:
48 = π * radius^2
To find the radius, we need to solve for it. Let's rearrange the equation to isolate the radius:
radius^2 = 48 / π
Now, we can take the square root of both sides to solve for the radius:
radius = √(48 / π)
To evaluate this equation, we need to know the approximate value of π. π is a constant value which is approximately equal to 3.14159.
Substituting the value for π into the equation, we get:
radius = √(48 / 3.14159)
Now, we can use a calculator to find the square root of (48 divided by 3.14159) and get the value of the radius.
After calculation, the radius would be approximately 3.486 feet.
