If the area of a circle is 25 square units what is the radius of the circle?
area equals pi r squared therefor r squared equals area over pi. Now find square root of r squared and you have "R" (radius) = 2.821
How do you find the bottom half of a circle?
To find the area of half a circle, use the formula for a circle pi*r^2 divided by 2. pi = 3.14, r = radius (half the distance across the circle)
How does area of a circle relate to circumference?
The area of a circle is equal to the perimeter times half the radius. That is, A = P*r/2
What is the area of a circle with a diamerer of 24 meters use 3.14?
area of a circle = pi*r^2 with pi being 3.1415926535..... that is the ratio between the diameter of the circle and it's circumference. r stands for radius (half the diameter if you didn't know) so for this circle to find the area all you have to do is 12 (half of 24 the diameter to find the radius) , then square it (144) then times it by pi which equals approximately 452.39 meters^2
What is the area of a circle if the diameter is 5?
The area of a circle is pi multiplied by "'r' (radius) squared""r" is 2.5 (half of the diameter)"r squared" is 2.5*2.5 which is 6.25.In terms of pi, the area of the specified circle is 6.25[pi] units squaredPi's rounded answer is 3.14. So in an answer not in terms of pi, you would multiply 6.25 and 3.14. That equals 19.625 units squared
