Step-by-step explanation:
diameter = 4cm
radius = 4/2 = 2cm
height = 3cm
volume of cylinder = πr²h
= 22/7 × 2 × 2 × 3
= 264/7cm³
= 37.714cm³
Answer:
6
Step-by-step explanation:
Answer:
well the height of the triangle would be 5, the base is 12. The area of a triangle is the height times the base divided by 2 so 12 times 5 = 60 divided by 2= 30.
Divide both sides by 2 2(x+2)=-
move constant to the right x+2=-2
calculate x=-2-2
x=-4
I believe is 4.9. I hope that helps
