Select the correct answer. A cone is placed inside a cylinder as shown. The radius of the cone is half the radius of the cylinder. The height of the cone is equal to the radius of the cylinder. What is the volume of the cone in terms of the radius, r? A. B. C. D.

V =

Step-by-step explanation:

Volume of Cone =

But, Given that radius of cone = r/2 of the cylinder

And,

Height of cone = Radius of cylinder i.e. h = r

Putting this in the above formula.

=> V =

=> V =

=> V =

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
