What is the radius of a circle whose area is 616 square meters?
Well, isn't that just a happy little question! To find the radius of a circle when you know the area, you can use the formula A = πr^2. In this case, the area is 616 square meters, so you can plug that in and solve for the radius. Just remember to take a deep breath, trust in your math skills, and enjoy the process of finding the radius of this circle.
How do you find the area of the circle if the radius is 5m?
Use the formula: A = pi x r2. That is, area = pi x radius squared.
What is the area of a circle with radius of 4cm?
A circle with a radius of 4 cm has an area of 50.27 square cm.
If the area is 628 what is the radius of a circle?
To find the radius of a circle with a given area of 628, you can use the formula for the area of a circle, A = πr^2, where A is the area and r is the radius. Rearranging the formula to solve for the radius, you get r = √(A/π). Substituting the given area of 628 into the formula, you get r = √(628/π) ≈ √(199.87) ≈ 14.14. Therefore, the radius of the circle is approximately 14.14 units.
What is the area of a circle with the radius of 9.2 cm?
Just use the formula for the area of a circle. A = pi x r2. Replace "pi" with 3.1416, and "r" with the radius you know. The answer will be in square centimeters.
How do you find the circumfrence of a circle when you have the area?
Divide the area by pi then square root your answer which will give the radius of the circle and use 2*pi*radius to find the circumference.
How do you find the radius of a circle if area is 81 pi?
Divide the 81 pi by pi, then square root it. (Use the formula for area of circle, which gives 81pi=pi*radius squared, but rearrange to find the radius). i.e. it's the square root of 81
How do you find the area of a circle in a square?
To find the area of a circle inscribed in a square, you can use the formula for the area of a circle (πr^2) and the properties of a square (all sides equal). Since the diameter of the circle is equal to a side of the square, you can find the radius of the circle by halving the side length of the square. Then, plug the radius value into the area of a circle formula to find the area.
How do you find the center and radius of a circle?
just use the area formula ex... area of circle= pi(r square) if you know what your area is then plug it in then do PI / by area that will be your diameter to get the radius / your answer by 2
What is the radius of a circle with an area of 32.1 square feet?
To find the radius of a circle given its area, you can use the formula for the area of a circle, A = πr². Rearranging this formula to solve for the radius gives r = √(A/π). Substituting the given area (32.1 square feet) into the formula, the radius is r ≈ √(32.1/π) ≈ 3.19 feet.
How do you work out the difference of the area of a circle and the area of a square when the radius of the circle is 6cm and the side of length of the square is 12cm?
Do you know how to find the area of a circle when you know the radius ? Good! Do that. Do you know how to find the area of a square when you know the length of the side ? Good! Do that. Now you have two numbers ... the area of the circle and the area of the square. The problem wants you to find the difference of these two numbers.

How many square miles in a 10 mile radius?
To find the area of a circle with a 10-mile radius, you can use the formula for the area of a circle, which is ( A = \pi r^2 ). Plugging in the radius, ( A = \pi (10)^2 = 100\pi ) square miles. This is approximately 314.16 square miles.
How do you find a radius?
There are several of ways to find a radius, it depends on what information you already have. One way is of course to measure from the center of the circle to any point on the edge. Another is to use the formula, radius = square root of area / square root of pi.

How do you Find the area of the circle use the pie of 3.14?
You use the formula: area = pi x radius squared If you approximate pi with 3.14, and replace the square with a product, that becomes: area = 3.14 x radius x radius
What is the radius of a circle whose area is 1256 square centimeters?
To find the radius of a circle given its area, you can use the formula A = πr^2, where A is the area and r is the radius. In this case, the area is 1256 square centimeters. So, 1256 = πr^2. To solve for r, divide both sides by π and then take the square root. Therefore, the radius of the circle is approximately 20 centimeters.
How do you find the radius of a circle with an area of 100 pie meters?
Use the equation: Area of Circle = pi * r^2 so... 100 pi = pi * r^2 The pi's cancel out. 100 = r^2 Square both sides to find the radius. square root(100) = r, the radius of the circle
