semi means half
A semi-circle is half a circle
The formula for the area of a circle is
A = (Π * r^2)

What is the formula for the surface area of a rhomboid?
what is the formula to finding the total surface area of a rhomboid?!
How is the formula for finding the lateral area of a cylinder like the formula for finding the area of a rectangle?
L.A.= 2*pi*radius*height its not like finding the area of a rectangle. a cylinder is a 3-D shape and a rectangle is a flat shape
What is area of semicircle?
The area of a semicircle is half of the area of a circle. The area of a circle is pi x radius x radius. So the area of a semicircle is 1/2 x pi x radius x radius or (pi x radius x radius) / 2.
What is the area of a semicircle when the radius is 21?
The equation for area of a circle is A=pi x R x R. A semicircle is half a circle, so we calculate the area of a circle and divide by 2. The area of the circle would be approximately 1384.74. Thus the area of the semicircle would be 692.37.
How do you find the radius of a circle when the area is given?
-- Take the formula for the area of the circle in terms of the radius . . . A = (pi) R2-- Solve that formula for 'R'. You'll then have a formula for the radius in terms of the area,which is exactly what you're looking for.
What is the formula to find the area of a semicircle?
Pi*radius squared is how to find the area of a semicircle
What is the formula for the volume of a sphere in terms of surface area S?
Given the surface area, where S=surface area, the formula for finding the volume isV = √(S / 4pi)
Is the formula for finding the area of an oval the same as the formula for finding the area of a circle?
No because the formula for finding the area of an oval, which is an ellipse, is quite different
What is the formula for a semi-circle?
There is no formula for a semicircle. There is a formula for the perimeter of a semicircle, a different formula for the area of a semicircle, and another one to generate a semicircle in the Cartesian plane. You must specify which of these you want a formula for. Also, there may be additional information that is required to put the formula in the context of the available information. For example, the formula for the area will differ depending on whether you know the length of the straight side or the semi-circular arc.
What is the formula for finding the area of an ellipse?
the formula for finding the area of an ellipse is add it then multiply and subtract that is the final
How do you find the area of a semi-circle radius 10cm?
πr² is the formula for finding the area of a circle. To find the area of a semicircle just divide the answer by two. So take the radius, square it, which in this case would be 100, multiply it by π [pi (3.14)] and divide it by two.
What is the formula of area semicricle?
The area of a semicircle is one-half the area of a circle. it is equal to (pi/2)r^2, where r is the radius.
What is the area of the semicircle (use 3.14 for and rho)?
That would depend on the radius which has not been given but the area of the semi circle will be (pi*radius squared)/2
What is the equation to solve the area of a semicircle?
Area of a semicircle = (pi*radius^2)/2
What is the formula for finding the area of a semi circle in terms of pi?
Well the formula for a full circle is 3.14xradius squared So cut the radius in half then square it the multiple by 3.14
What is the formula for the surface area of a rhomboid?
what is the formula to finding the total surface area of a rhomboid?!
What is the formula of finding the surface area of a circle?
This is normally expressed in terms of the radius: area = pi x radius2.This is normally expressed in terms of the radius: area = pi x radius2.This is normally expressed in terms of the radius: area = pi x radius2.This is normally expressed in terms of the radius: area = pi x radius2.
