How do you find the area of a semicircle using pi?

To find the area of a semicircle, you first need the radius (r) of the semicircle. The formula for the area of a full circle is ( A = \pi r^2 ). Since a semicircle is half of a circle, you divide that area by 2: ( \text{Area of semicircle} = \frac{1}{2} \pi r^2 ). Thus, the area of the semicircle can be expressed as ( \frac{\pi r^2}{2} ).

How do you find out the displacement of a semicircle?

To find the displacement of a semicircle, you can calculate its area and use that to determine the center of mass. The area of a semicircle is given by the formula ( A = \frac{1}{2} \pi r^2 ), where ( r ) is the radius. The center of mass for a semicircle lies along the vertical axis at a distance of ( \frac{4r}{3\pi} ) from the flat edge. By using these values, you can find the displacement in terms of both area and center of mass position.

How do you find the area of circle when its half of the circle?

Find the area of the whole circle and divide by two. Area of semicircle = 0.5*pi*r2, where pi = 3.14159 and r is the radius


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 the semicircle if the length of the arc of a semicircle is 10 and pi feet?

It is 27.49 units.


Calculate the area of semicircle with radius 4 meters?

An area of a circle is pi*r2 - so an area of a semicircle is 0.5*pi*r2: 0.5*3.14*42 = 25.13 square meters


What is the area outside the triangle if the triangle is inscribed in a semicircle while the side length of triangle is 2underroot2?

Diameter of semicircle = 1 Area of semicircle = Pi/8 Area of triangle = 0.25 Area outside triangle = (Pi/8) - 0.25 = 0.1427 (rounded to 4th decimal).


What is the perimeter and area of a semi circle that has a radius of 4 inches?

The circumference of a circle is 2{pi}r. So, for a semicircle it is half this, that is {pi}r. The perimeter of the semicircle is the round bit ({pi}r) plus a diameter of the circle (2r) perimeter = {pi}4 + 2 x 4 ~= 20.6 in Area of a circle is {pi}r2, so for a semicircle it is half this. area ={pi}42 / 2 ~= 25.1 in2.
