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 = \frac{1}{2}\pi r^{2} h

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 = \sqrt{6^2-r^2}

[By Pythagoras theorem, l² = h² + r² ⇒ h = \sqrt{l^2-r^2}]
