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 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.
What is the radius of a circle when the area is 706.9?
The area of a circle is found by the equation pi times r2. To calculate the radius from the area we need to divide the area by pi and get the square root of the result. if we use 3.1418 as a close approximation of pi, we get 706.9 ÷ 3.1418 = 225 and the square root of 225 = 15.
What is the area of 47.1 rounded to the nearest tenth?
47.1
Shell script to find area of a circle?
To write a shell script to find the area of a circle, you can use the formula: area = π * radius^2. Here is an example shell script using the read command to input the radius from the user: #!/bin/bash echo "Enter the radius of the circle:" read radius area=$(echo "3.14159 * $radius * $radius" | bc) echo "The area of the circle with radius $radius is $area" This script first prompts the user to enter the radius, calculates the area using the formula, and then displays the result.
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
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. Do you know how to use subtraction to find the difference of two numbers ? Good! Do that.
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 calculate m2 of a circle?
The surface area of a circle is calculated as Area = pi x radius2. If the radius is in meters, the area will be in square meters.The surface area of a circle is calculated as Area = pi x radius2.

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
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
How do you find the area inside a circle?
use the equation Area=pi*r2 r is the radius of a circle If you are presented with the diameter of the circle, divide by 2 to receive the radius. Now, square and multiply by pi.
How do you convert radius miles into square miles?
To convert radius miles into square miles, you would need to use the formula for the area of a circle: A = πr^2, where r is the radius. Square the radius value, then multiply it by π (approximately 3.14) to get the area in square miles.
