Answer:
the volume of the solid is 1024/3 cubic unit
Step-by-step explanation:
Given the data in the question,
radius of the circular disk = 4
Now if the center is at ( 0,0 ), the equation of the circle will be;
x² + y² = 4²
x² + y² = 16
we solve for y
y² = 16 - x²
y = ±√( 16 - x² )
{ positive is for the top while the negative is for the bottom position }
A = b²
b = 2√( 16 - x² ) { parallel cross section }
A = [2√( 16 - x² )]²
A = 4( 16 - x² )
Now,
VOLUME =
=
= 4[ 16x - (x³)/3 ] { from -4 to 4 }
= 4[ ( 64 - 64/3 ) - (-64 = 64/3 0 ]
= 4[ 64 - 64/3 + 64 - 64/3 ]
= 4[ (192 - 64 + 192 - 64 ) / 3 ]
= 4[ 256 / 3 ]
= 1024/3 cubic unit
Therefore, the volume of the solid is 1024/3 cubic unit
Answer:
C = (g + 5)
Step-by-step explanation:
Given the cost of a customers smartphone bill,
C=10g+50
We are required to factor the polynomial.
First, determine the G.C.D of both terms
The GCD of 10g and 50 is 10
Next, we divide each of the term by 10 and balance it by multiplying the expression by 10.
C = 10g + 50
= 10 (10g / 10 + 50/10)
The cost polynomial factored is C=10(g+5).
Answer: 1.6, but if your looking for rounding numbers, its 2. I suggest 1.6 though.
Step-by-step explanation: hope this helps :)
(A)
This is because you have to add $8 to your total bill, so you add 8 to the snacks you buy for you and your friend (2 x)
Also, 22 is the max amount you can use, and you don't add anything to your budget when you buy things.
