Answer:
Step-by-step explanation:
In this problem we know that a DVD costs $238 dollars.
Adrian bought 18 DVD's in total.
Meaning that since each DVD costs $238, we will have to multiply 18 by 238
==>
Now, here is the difference, the question asks <u>approximately</u> how much he will spend.
Meaning that we need to round to find our approximate.
4124
==> 4300
You could also say around 4000 to 5000 dollars
Answer:
Radius = 11.85yd
Step-by-step explanation:
Volume of a Cone formula: V = πr²(h/3)
We know that;
V = Volume
r = radius
π = pi (this is a sign located on your calculator)
h = height
We are given that;
V = 4,410
r = unknown
h = 30
Let's substitute the values in:
=> V = πr²(h/3)
=> 4,410 = πr²(30/3)
=> 4,410 = πr²(10)
=> 4,410 / 10 = πr²
=> 441 = πr²
=> 441 / π = r²
=> 140.37 = r²
=> = r
=> 11.85 = r
Therefore, <u>the radius of the cone = 11.85yd</u>
Hope this helps!
