1. A new ice cream shop is opening up and the owners are making a large ice cream cone for display What is the volume of the ice cream cone? Round your answer to the nearest hundredth of a
cubic inch. Use 3.14 to approximate pi. Show your work and explain your steps.
radius = 4 and height =10

167.47 cubic metres

Step-by-step explanation:

Volume of a cone is given by where r is radius and h is the height of the cone. Assuming a radius of 4m and height of 10 m then the volume, using 3.14 for will be

V=

the answer is 14ft

step-by-step explanation:

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)
