Given that the area of a circle is 625Pie, find the diameter of the circle.
The formula for the area of a circle is A = πr^2, where A is the area and r is the radius.
In this case, the given area is 625π. So we have:
625π = πr^2
To find the radius, we can divide both sides of the equation by π:
625 = r^2
Taking the square root of both sides, we get:
r = √625
Since the radius is half of the diameter, the diameter will be twice the radius:
Diameter = 2r
So, the diameter of the circle is:
Diameter = 2√625
Simplifying this expression, we have:
Diameter = 2 * 25
Diameter = 50
To find the diameter of the circle, we need to use the formula for the area of a circle, A = πr², where A is the area and r is the radius.
Given that the area of the circle is 625π, we can set up an equation:
625π = πr²
To isolate the radius, we divide both sides of the equation by π:
625π/π = πr²/π
625 = r²
To find the radius, we take the square root of both sides of the equation:
√625 = √r²
25 = r
Now that we have the radius, we can find the diameter by multiplying the radius by 2:
d = 2r
d = 2(25)
d = 50
So, the diameter of the circle is 50 units.
A = pi * r^2
625 = 3.14 * r^2
625/3.14 = r^2
199.045 = r^2
14.108 = r
d = 14.108 * 2
d = ?
