Answer: 28.26
Step-by-step explanation:
What your looking for is called the annulus (or the difference of two concentric circles). You can find the annulus by subtracting the area of the inner circle from the area of the outer circle. Volume of a circle= πr²
You are given the diameter in these problems, so you need radius.
For the first circle (8 in one) :
8/2=4 r=4
A=3.14(4)²
A=50.24
For the second one (10 in one) :
10/2=5 r=5
A=3.14(5)²
A=78.5
To find the measure of the annulus, you subtract those numbers, getting 28.26

Answer:
Step-by-step explanation:
Given:
Required:
LCM of the polynomials
SOLUTION:
Step 1: Factorise each polynomial
Step 2: find the product of each factor that is common in both polynomials.
We have the following,
The common factors would be: =>
(this is common in both polynomials, so we would take just one of them as a factor.
and,
Their product =
