To find the area of a circle inside a right angled triangle, we have the formula to find the radius of the right angled triangle, r = ( P + B – H ) / 2. Given
Read on to learn how to find the area of a quadrant! Michael Daly | Wikimedia Commons What Is a Quadrant? A quadrant is a quarter of a circle. So, to work out the area of a quadrant, first work out the area of the whole circle (use the formula A = π×r²) and then ...
How to Find the Area of a Rectangle when Perimeter is Given? The area of a rectangle can be calculated if the perimeter and one of its sides is given. With the help of the perimeter, we can find the missing side and then calculate the area of a rectangle using the same formula, Area...
What is the formula to find the radius? If the diameter of a circle is known then the formula for radius is diameter divided by 2. If the circumference of a circle is known then the formula for radius is the circumference divided by 2 pi. And if the area of a circle is known then...
The formula for the area of a circle is "pi x r2" where "r" is the radius of the circle. So if you have a pool with a diameter of 20 feet, the radius is 10 feet, and the formula would be calculated in this way: 3.14 x 102= 314 square feet. ...
