dimaraw [331]

Arithmetic sequence

Explanation

An arithmetic sequence is a list of numbers with a definite pattern. If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence

Step 1

Let

$\begin{gathered} a_1=5 \\ a_2=7 \\ a_3=9 \\ a_4=11 \end{gathered}$ $\begin{gathered} a_2-a_1=7-5=2 \\ a_3-a_2=9-7=2 \\ a_4-a_3=11-9=2 \end{gathered}$

so, the difference is always the same, 2

Hence, the answer is a Arithmetic sequence

Find the volume and surface area of the composite figure. Give four answer in terms of π. HELP NEEDED NOW!!! THE RED IS THE ONE

asambeis [7]

Answer:

Divide the figure above into a cylinder and a dome

+) the volume of the dome is

$v1 = \frac{1}{12} \pi6 {}^{3} = 18\pi$

the surface area is

$s1 = \pi3 {}^{2} = 9\pi$

+) the volume of the cylinder is

$v2 = \pi.3 {}^{2} .13 = 117\pi$

the surface area is

$s2 = 2\pi.3.13 + 2\pi.3 {}^{2} = 96\pi$

so the volume of this figure is

$v = v1 + v2 = 18\pi + 117\pi = 135\pi$

the surface area of this figure is

$s = 9\pi + 96\pi = 105\pi$
