$\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\ \cline{1-1} r=9\\ h=7 \end{cases}\implies V=\pi (9)^2(7) \\\\\\ V=\pi (81)(7)\implies V=567\pi \implies V\approx 1781.28\implies \stackrel{\textit{rounded up}}{V=1781}$

Hello from MrBillDoesMath!

Answer:

a(n) = -3n , n>= 1

Discussion:

a(1) = -3

a(2) = -6

a(3) = -9

a(4) = -12

The pattern looks like a(n) = -3n

Thank you,

The segments in each figure are tangent to the circle. Find each length.

zubka84 [21]

The tangents are equal length, so
.. 8x = x^2
We presume their length is not zero, so we can divide by x to get
.. 8 = 2x
.. 4 = x

Then the length of each tangent is 8*4 = 32 units.

Answer:

Option D

Step-by-step explanation:

Use the Pythagorean theorem to solve this question

a2+b2=c2

c2 is always the hypotenuse, which is what we have to solve.

3^2+ 5^2=

9+25=34

Now we have to square 34 and there is our answer
