The preimeter square of a circle with radius r centimetres would be pi^2*r^4 centimetres squared. By the way, in more than 35 years as a mathematician, I have not come across perimeter square! I would be interested to know the reason behind this question.
a hemisphere
Each side measures 10 cm
semicircleA half circle is called a semicircle.Half a circle is a semi-circle
A part of a circle between two points on a circle is called is called an arc.
a number of a frason
It is the total distance around the lot.
p= 2 x (l + w)

you have to add all the sides up, thats all thabk you :)
