Daniel has a chicken farm. The old feed bin for his chickens was a cone-shaped bin that had a radius of 10 feet and a height of 12 feet.

He is getting a new cylinder-shaped bin for his feed. The new bin has a radius of 5 feet.

How tall must the cylinder be to hold the same amount of feed as the old cone-shaped bin?

Astudent is determining the influence of different types of food on the growth rate of spiders. she feeds one group of spiders two caterpillars twice a week. the other group received similarly-sized beetles twice a week. she records the amount of time required for individuals to reach sexual maturity. her hypothesis is that the spiders feeding on caterpillars will have a faster growth rate because caterpillars have a higher protein content compared to beetles. in this experiment, what is the dependent variable? spiders assigned to different feeding groups. time required to reach sexual maturity number of prey items fed twice a week. growth rates of each group.
