the area of a cirlce is 460ydsq. Find the radiusbof the circle.
pi r^2 = 460
r^2 = 460/pi
r = sqrt (460/pi) = 12.10051849 yds approximately
To find the radius of a circle when given its area, you can use the formula:
Area of a circle = π * radius^2
In this case, you know the area is 460 square yards. Let's substitute this value into the formula and solve for the radius:
460 = π * radius^2
First, divide both sides of the equation by π:
460 / π = radius^2
Now, take the square root of both sides to isolate the radius:
√(460 / π) = radius
Using a calculator, divide 460 by π, then take the square root of the result to find the radius. The final answer will be the approximate value because π is an irrational number.
I will calculate the approximate radius value for you.
