**Find the maximum area of the semi-circle with a perimeter**

Math. The perimeter of a semicircle is 72 cm. Find the raduis of the semicircle and then find its area Consider the full circle: perimeter 144 radius= perimetercircle/2PI areacircle= PI…... Formula to find Perimeter of semicircle = pi x r (where r is radius of circle) So, pi x r =4pi + 8 => 3.14 x r = 4 x 3.14 + 8 => 3.14r = 12.56 + 8

**How do we find a perimeter of a semicircle? answers.com**

First find the perimeter of the semi circle = pi d divided by two Then subtract the 17 from 44 which is perimeter of the rectangle Now add the perimeter of the semicircle with the answer we just got... 30/09/2009 · The area of a circle is pi R^2 so if the diameter is 12cm, the area of the circle will be 36pi sq cm. The area of a semicircle will be half that so it is 18pi sq cm. The circumference of a circle is 2piR so that is 12 pi cm. The curved part of the semicircle will be half the circle so that will be 6pi. You then need to add a diameter so the perimeter of the semicircle will be 6pi + 12 cm

**Find the maximum area of the semi-circle with a perimeter**

Hi Sarah, Since this question mentions the perimeter of a semicircle we would like to find a formula for such an object. The perimeter is composed of two parts; the diameter of the circle (d=2*r) and half the circumference of a full circle (pi*r). how to get gold duke of edinburgh award Units count. Use the same units for all measurements. Examples. square = 4a. rectangle = 2a + 2b triangle = a + b + c . circle = 2pi r . circle = pi d (where d is the diameter) The perimeter of a circle is more commonly known as the circumference. Units. Be sure to only add similar units. For example, you cannot add inches to feet. For example, if you need to find the perimeter of a rectangle

**Find the perimeter of the figure. If you need to use pi in**

Hi Sarah, Since this question mentions the perimeter of a semicircle we would like to find a formula for such an object. The perimeter is composed of two parts; the diameter of the circle (d=2*r) and half the circumference of a full circle (pi*r). how to get your soundcloud tracks out there First, we know that the equation for permeter of a circle is C=2*pi*4 or C=2*3.14*r if you are using 3.14 for pi. Since this is a semicircle, we simply divide this equation by 2 and plug in our radius (radius id 6 because 12/2 =6)

## How To Find The Perimeter Of A Semicircle Using Pi

A semicircle can be used to construct arithmetic and geometric means of two lengths using straight-edge and compass. If we make a semicircle with a diameter of a+b, then the length its radius is the arithmetic mean (since it's half of the diameter).

- The perimeter of a circle is most commonly referred to as the circumference of a circle and we will use the word Now to calculate the circumference of the circle we multiply pi (∏) by the diameter (d) of the circle. ∏ is a fixed value equal to 3.14, or to be exact 3.1415926535897932384 but = 3.14 will do for our calculations. Calculating the circumference using diameter. We now know
- First, we know that the equation for permeter of a circle is C=2*pi*4 or C=2*3.14*r if you are using 3.14 for pi. Since this is a semicircle, we simply divide this equation by 2 and plug in our radius (radius id 6 because 12/2 =6)
