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...
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 To Find A Radius For Hollow Objects? The radius of a sphere or a circle is the distance from its center to its circumference. For any regular polygon, the radius is the same from the center to all its vertices. A circle is a regular polygon where the distance from the center to ...

How do you find the area of a circle with a diameter of 6? If we have a circle in a square and r is the radius of the circle and x is the measurement outside the square. What will be the formula to find the area of the whole square using x...
A cylinder has base area 56 in^2, height 6 in. Find the volume. Find the surface area of a cone with height h and base radius a (excluding the base). 1) Solve for r. V = \pi r^2h. 2) Use the formula V = \pi r^2h to find the radius of a cy...
In high school geometry, you will study arcs, or segments of a circle. No matter what the size of the arc is, you can use it to determine the radius and size of the circle to which the arc belongs. This skill is useful for construction and engineering ap
Using the curvature of the Earth relative to the parallel light from the sun, we can observe shadows at different locations on the surface of the Earth to find the Earth's radius. Record the Distance Record the distance between your location and your partner's location. As an example, we ...
To find the area of a sector of a circle, use this formula: The area of a sector \(=πr^2 (\frac{θ}{360})\), \(r\) is the radius of the circle, and \(θ\) is the central angle of the sector. To find the arc of a sector of a circle, use this formula: ...
Example 1: If the radius of a circle is 30 cm, find its circumference. Solution: r = 30 cm Use the formula to find the circumference of a circle: C = 2\(\pi r\) [Write the formula] = 2 x 3.14 x 30 [Substitute the value of r and \(\pi\)] = 6.28 x 30 = 188.4 Therefor...
