Hi :)
The find out the circumference of M,we'll need to calculate diameter (AC)
We can calculate AC with Phytagora's formula :
AC²=OC²+OA²
AC²=6²+8²
AC²=100 ⇒ AC = 10
Circumference : D*π = 10*π = 10*3,14159 ≈ 31,4159 m
Since the diameter is 6 cm, the radius is 3 cm. Use the area formula to get 113.04 cm squared. Then, you multiply that by the height of the rod, which is 20 cm. The volume of one rod is 2260.8 cm cubed. To find how much steel is needed for 189 rods, multiple the volume of one rod by 189. Your answer should be 427291.2 cm³.
3 is a greater value than -8
