Question

1. After teaching about the world’s biggest ice cream cone Mr. Kamp decided to make one of his own. Approximately how much ice cream will he need to buy? Use the dimensions below to find out how much ice cream to purchase. Round your answer to the nearest tenth of a cubic inch. Use 3.14 to approximate pi.

Answer 1

I think it is 6104.2 in.^3

3.14*9*9*14=3,560.76 3,560.76/3=1,186.92 (3,052.1) 3.14*9*9*4=9,156.24 9,156.24 /3=3,052.08 (3,052.1) 3,052.1+3,052.1=6104.2

Answer 2

das is hemisphere+cone
hemisphere=sphere times 1/2

vcone=(1/3)hpir^2
Vhemisphere=1/2 times Vsphere=1/2 times (4/3)pir^3=(2/3)pir^3


calculate seperate for simplicity of reading
cone
height=14
radius=9
V=(1/3)(14)(pi)(9^2)
V=(1/3)(14)(pi)(81)
V=378pi in^3

hemisphere
radius is 9
V=(2/3)pir^3
V=(2/3)pi(9^3)
V=(2/3)pi(729)
V=486pi in^3
addd to find toatl


cone+hemisphere=378pi+486pi=864pi
using 3.14=pi
Vtotal=2712.96 cubic inch
nearest tenth
Vtotal=2713.0 cubic inch
