1. Draw a circle
2. Keeping your compasses open the same distance stick the point on the edge of the circle and draw two little arcs that cut the circle.
3. Stick the point in one the arcs and draw another arc further along the circle. Repeat until you have 6 arcs marked.
4. Use a ruler or straight edge to join up the arcs.
Since the radius of the semi circle is 10 cm then the diameter is 20 cm, when folded, its circumference is now 20, given the circumference find the radius of the cone. i guess
Volume = 1/3 πr2 (l2﹣r2)1/2
circumference = 20 cm = πD
D=6.363636364
Radius = 6.363636364/2 = 3.181818182
l = 10
vol = 100.51cm3
curved s.a = πrl
=99.96cm2
80+32=112 so all you do is just add or use a brain .
we have the expression
Evaluate for x=-4/5 and y=1/3
substitute the values of x and y in the given expression
the answer is 32/15
It will take 13 weeks to save the money to buy the equipment because if you subtract 20 you get 55.25 then divide by 4.25 you get 13 <span />
