She can make 14 spikes maximum
Step-by-step explanation:
The formula of the volume of a cone is V =
π r² h, where
- r is the radius of its base
- h is its height
∵ The spikes are shaped like right circular cones with base
radius of 2 inches and height of 6 inches
∴ r = 2 inches
∴ h = 6 inches
- Use the formula above to find the volume of each spike
∵ V =
(π)(2)²(6)
∴ V ≅ 25.13274 inches³
∵ Daisy has 360 cubic inches of material for making the spikes
- To find the number of spikes she can make divide the volume
of the material by the volume of each spike
∴ The number of spikes = 360 ÷ 25.13274 = 14.324
- The number of spikes must be an integer
∴ The maximum number of spikes she can make is 14
She can make 14 spikes maximum

V=4/3 πr^3would be the formula
Answer:
17.7 as the actual gas mileage recorded is 12 mpg.
Step-by-step explanation:
Answer:
62.84
Step-by-step explanation:
Volume of both cones is approximately 12.57
formula= pi*r^2*h/3
Volume of the cylinder is approximately 37.7
formula= pi*r^2*h
you add the volumes
12.57+12.57+37.7
= 62.84
