Answer:
<h3>volume = 23.86in³</h3><h3>surface area = 16π in²</h3>Step-by-step explanation:
Given the diameter of the base of the cone = 4.0inches
radius of the cone = 4.0/2 = 2.0inches
slant height l = 6.0inches
Volume of the ice cream that made the cone = 1/3
to get the height of the cone we will use the Pythagoras theorem.
According to the theorem,
given hyp = slant height = 6in
adjacent = base radius = 2in
height = opposite
opp =
opp =
opp = height = 5.7in
Volume = 1/3 * 3.14 * 2² * 5.7
volume = 23.86in³
For the surface area;
Surface area of a cone = πr(r+l)
surface area = 2π(2+6)
surface area = 16π in²
