`r = sqrt((2*V)/(pi*h))`

Enter a value for all fields

The Radius of a Semicircle Volume calculator computes the radius of a semicircular shape based on the volume (V) and the height (h). /attachments/2e608e65-a535-11ea-952b-bc764e203090/Semi-circle Volume.png

INSTRUCTIONS: Choose units and enter the following:

(h) This is the height of the semicircle shape
(V) This is the volume of the semicircle

Semicircle Radius (r): The calculator returns the radius in meters. However, this can be automatically converted to compatible units via the pull-down menu.

The Math / Science

The formula for the volume of a semicircle is:

V = ½•π•r²•h

where:

V is the volume of the semicircle
h is the height of the semicircle
r is the radius of the semicircle

If you solve the above equation for the radius of the semicircle volume you get:

`r = sqrt((2*V) / (pi*h))`
