Answer:
v=23160.24
Step-by-step explanation:
v= r^2 * h * π
19.6 ^2 = 384.16 r = d/2
384.16 * 19.2 * 3.14 39.2 / 2 = 19.6
23160.24
Hope this isn't too confusing!
In order to solve for a nth term in an arithmetic sequence, we use the formula written as:
an = a1 + (n-1)d
where an is the nth term, a1 is the first value in the sequence, n is the term position and d is the common difference.
First, we need to calculate for d from the given values above.
<span>a1 = 38 and a17 = -74
</span>
an = a1 + (n-1)d
-74 = 38 + (17-1)d
d = -7
The 27th term is calculated as follows:
a27 = a1 + (n-1)d
a27= 38 + (27-1)(-7)
a27 = -144 -----------> OPTION D
It would be perpendicular expression
Answer:
SA= 552.92
Step-by-step explanation:
You are solving for the surface area of a right cylinder. The equation for a right cylinder is:
SA=2πrh+2πr^2
The radius is 8 and the height is 3 so plug those in:
A=2π(8)(3)+ 2π(8)²
Solve this out using pie as 3.1415
The answer would be 552.92
Answer:
12-2(n-1).
Step-by-step explanation:
It can be written 12-2n+2=14-2n, so that when n=1, the 1st term is 14-2=12. The 5th term is 14-10=4; the 6th is 14-12=2.
