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!
Answer:
about 463 minutes or 7.7 hours
Step-by-step explanation:
area=length*width
4.75ft*3.25ft=15.4375ft^2
Now multiply 15.4375*30 to get 463.125 minutes

Answer:
The answer to your question is z = 87 cm
Step-by-step explanation:
Data
Surface area of the rectangular prism = 8,462 cm²
Find z
Process
1.- Write and equation that help to solve the problem
Surface area = 2(13z) + 2(13)(31) + 2(31z)
-Simplify
8462 = 26z + 806 + 62z
8462 - 806 = 26z + 62z
7656 = 88z
z = 7656/88
-Result
z = 87 cm
