Answer:
The side of the triangle
a=8cm
b=20cm
c=16cm
Step-by-step explanation:
Perimeter = 44 cm
a= x
b=2x+4
c=2x
So the perimeter of a triangle is the sum of its sides
a= 8cm
b=2*8+4=20 cm
c= 2*8= 16 cm
Check:
a+b+c=44cm
(8+20+16)cm=44cm
44cm=44cm
I can't really see the whole question, but for a cone the volume formula is πr2h
