Therefore, by substituting the . First we calculate "h": h = (a b)2 (a + b)2 Then use it here: p (a+b) ( 1 + 3h 10 + (43h) ) Infinite Series 1 This is an exact formula, but it needs an "infinite series" of calculations to be exact, so in practice we still only get an approximation. Thus, r = 144 (7/36) = 28 units, We know that the area of a semicircle, A= (r2)/2 Solution: Given the perimeter of semicircle is 144 units. That will therefore be Formula for the circumference (perimeter) of a semicircle using its diameter = ()d + d Substitute the value of d, we get; = () (22/7) 7 + 7 = 11 + 7 = 18 Therefore, the perimeter of the semicircle is 18 cm. The length of an arc = 2r (/360) = 2 x 3.14 x 24 x 120/360. It is calculated by adding the length of the diameter and half the circumference of the original circle. $c=\pi*D/2+D$, where $D$ is diameter of course,but in problem,link of which i have posted,it is not considered and it said that perimeter of half circle is just $\pi*D/2$,in case of this test come on GRE exam,i should now of course which formula is correct,so please help me to determine there is error made in formula $\pi*D/2+D$ or what? We can find the area of a semicircle when the circumference of the semicircle is given using the following steps: If the radius of the semicircle is doubled then the circumference will also get doubled. Now we find the circumference of half the circle. However, using a straight ruler, the fixer was able to find that the tyre diameter was 41cm. In algorithms for matrix multiplication (eg Strassen), why do we say n is equal to the number of rows and not the number of elements in both matrices? Perimeter of semicircle formula P=\pi r+d P = r + d Thus, it is given by the sum of half of the circumference of the circle and its diameter; 1/2 (d) + d or r + 2r, where d is the diameter and r is the radius of the semicircle. I hope i am clear. = 50.24 cm. so it means that,solution is wrong right? The area of a semicircle is half the area of a circle. It is not a polygon because it has a curved edge. Now, when you know the etymology, you won't forget what a semicircle is: just remind yourself how the semifinals are connected with the finals, and you'll know how to link a semicircle to a circle. Step: 4 The perimeter of the semicircle is determined by this value. So, now i guess you can see which formula is to be used.
