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 /...
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...

How to Find Arc Length Without the Radius? The arc length of a circle can be calculated without the radius using: Central angle and the sector area: Thesector areaformula is, (θ/360º) ×πr2, if θ is in degrees (or) (1/2) r2θ, if θ is in radians. ...
To find the area of a circle given the radius,plug in the value of the radius to the formula A = pi r^2. To do this, first you square the radius, then you multiply the result by pi. If the radius of your circle is 2, write out of your formula using 2 instead of r: A = ...
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 ...
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 divide the answer by 4. Alternatively, you could substitute the radius of the quadrant directly into the formula A = ¼ πr². Let’s take a look ...
r represents the radius of Earth, which is approximately 6400 kilometers or 3959 miles, A and B represent the latitudes of the two points, and X and Y represent the longitudes. How to Find Great Circle Distance Using an Excel Formula: Step-by-Step Procedure Step 1 – Arranging the Datase...
(s/r) = (arc's length / circle's radius) The resulting answer is written in radians, and can be converted to degrees by multiplying that number of radians by 180, then dividing by 3.14 (pi). (s/r) * (180 / 3.14) The circumference of a circle is found by using the formula 2 ...
