Answer:
C. 31.83 feet.
Step-by-step explanation:
We have been given that Trina has $1000 to purchase an open-top cylindrical dog pen in her backyard. She wants the height of the pen to be 5 feet.
First of all, we will find the surface area of dog pen using surface area of cylinder.
,where,
r = Radius of cylinder,
h = Height of cylinder.
Since the area of each square foot of pen costs $1, so in $1000 Trina can cover an area of 1000 square feet.
Now, we will set the surface area of cylinder equal to 1000 to solve for the radius.
Upon dividing both sides of our equation by 10 pi we will get,
Therefore, the radius of the dog pen is 31.83 feet and option C is the correct choice.
Given :
A small pot holds 25% as much dirt as a large pot.
To Find :
If the small pot holds 8 cups of dirt, How many cups of dirt does the large pot hold.
Solution :
It is given that small pot holds 25% as much as dirt.
It means that large pot can hold 4 times as small pot.
Let, large pot holds x cups of dirt.
Therefore, large pot holds 32 cups.
4+4 is 8 so 4+5 is 9.So the strategy is a double +1. That is the strategy.
