Answer:
1). a
2). b
3). c
4). d
Step-by-step explanation:
From the picture of a cone attached,
Radius of the circular top = r
Height of the cone = h
Slant height of the cone 'l' = 6
Area of the circular top of the cone with radius 'r' = πr²
Amount of space inside the cone = Volume of the cone = [tex]\frac{1}{2}\pi r^{2} h[/tex]
The amount of wrapper needed to cover the side of the ice cream cone, not including the circular top of the cone = πrl = πr(6 in.)
The vertical height 'h' of the cone when the cone is standing upright = [tex]\sqrt{6^2-r^2}[/tex]
[By Pythagoras theorem, l² = h² + r² ⇒ h = [tex]\sqrt{l^2-r^2}[/tex]]
