**How to determine the surface area of a half circle Quora**

Now add together half the surface area of a sphere with the area of the circular base to find the surface area of a hemisphere. Plug in the given radius to find the surface area. Make sure to round to places after the decimal.... The area of a circle is:pi*(r^2) where r is the radius of the circle. The area of a half circle is then given by:( pi*r^2)/2, just half the area of the circle.

**Circle Area Calculator Calculate Area of Circle**

Now add together half the surface area of a sphere with the area of the circular base to find the surface area of a hemisphere. Plug in the given radius to find the surface area. Make sure to round to places after the decimal....For a circle, the ratio of the area to the circumference (the term for the perimeter of a circle) equals half the radius r. This can be seen from the area formula Ï€r 2 and the circumference formula 2 Ï€r .

**How to determine the surface area of a half circle Quora**

If I understand your description correctly, we can figure out the area as follows: A rough estimate (taking the width as 8 instead of 7, which gives a half-circle) gives $\pi r l = 96 \pi \approx 300$. how to get a good youtube channel 5/03/2007Â Â· Best Answer: Well, a half-circle (semi-circle) has area of 1/2*pi*r^2.

## How To Find The Surface Area Of A Half Circle

### Surface Area of Circle Formula. Circle is nothing but the 2-D representation of a sphere. The total area that is taken inside the boundary of the circle is the surface area of the circle. When we say we want the area of the circle, then we mean surface area of the circle itself. When the length of the radius or diameter or even the circumference of the circle is already given, then we can use
