Plug in the area to find the radius if you know the area. If a = pi r^2 then r = the square root (sqrt) of the area divided by pi, or to put it in mathematical script, sqrt(a/pi). So, if the area is 3.14, we get: r = sqrt(3.14 / 3.14) r = sqrt(1) r = 1 Refe...
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
You can find the circumference of a circle by using the measurement of its diameter, radius or area. The circumference of a circle is the distance around the circle's edge from one point, meeting back at that point. Knowing how to calculate a circle's ci
Thus, the arc of a circle formula is θ times theradiusof a circle, if the angle is in radians. The arc length formula can be expressed as: arc length, L = θ× r, when θ is in radian; arc length, L = θ× (π/180) × r, where θ is in degrees, ...
To find the area of a circle, you take pi times the radius squared, or A = pi r^2. Using this formula, you can find the area of a circle if you know the radius -- or the diameter -- by plugging in your values and solving for A. Pi is approximated as 3.
The circumference a circle can also be represented in terms of the radius of the circle.We can define the radius of a circle in terms of the diameter through the relationship: d=2∗r Substituting this into the previous equation to find circumference of the circle, we get: ...
1 hour ago comment added stickynotememo Yes, of course we don't have a way to find the exact radius of curvature in real life. However, my question doesn't stem from a need to solve a real-life problem, but rather an interest in whether we could find the radius of curvature in a...
