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 the P, B and H are the perpendicular, base and hypotenuse respectively of a right angled triangle. where π = 22 /...
How do you find the radius and diameter of a circle? Measure the length from the center of a circle to a point on the boundary of a circle. That measure will give the radius of a circle. Multiplying the radius by 2 will give the diameter of a circle.Parts...
How do you construct the median of a triangle? Find the value of 90 - 9 + 123456789. Explain the Poisson formula in statistics. How to find the radius of a circle What is the derivative of y = 3/x^3? Without using a calculator find the exact values of arctan sqrt 3, arccos (sqr...
Answer to: Explain how to find the area of a quarter-circle and semi-circle. Give the formulas when the radius is r. By signing up, you'll get...
If we have the coordinates of two vertices of a triangle and the lengths of all the sides, then we can find the coordinates of the third unknown vertex. 1) We take the lengths of the two sides which has the unknown vertex in them. We draw circles with lengths as the radius from the...
To calculate the area of the octagon we can use the area of an isosceles triangle. We divide the area of the shape into eight equal isosceles triangles and calculate it accordingly. A regular octagon has the length of the sides equal and the angles between these sides are equal. The ...
Multiply the radius by 2. (The distance from the intersection of the two sides to the center is called the radius.) Tip Remember, to find the area of a triangle, multiple the base by the height and then divide by 2 Finding the Area of a Regular Hexagon ...
The area of a circle is 3.14*(radius*radius). To create the formula in Excel, I could suggest the exponential function however, since the goal is just to find the square, we can twist the formula a little. The syntax to find the area of a circle in Excel is as follows: ...
and you'll get 180 degrees. If you have a right triangle, one of its angles is 90 degrees by definition. That means the sum of the other two angles has to be 90 degrees, and if you know one of them, you can immediately find the other. But how do you find the angles if you do...
You can find the area of a circle by using the formula pi x radius^2, or pi x r^2. For example, the area of a circle with a radius of 3 would be 3.142 x 3^2. Therefore, the total area would be approximately 28.28. References ...
