Answer:

h = 6.7

Step-by-step explanation:

Find the Perimeter & Area for the following circle.

Feliz [49]

Answer:

A = 28.3 cubic inches; P = 20.1 inches

Step-by-step explanation:

<em>Looks like 3/4 of a full circle</em>

<em>The area of a circle is calculated with the formula: </em> $\pi r^{2}$

<em>Since the problem wants pi = 3.14, we use 3.14 instead of pi in the equation.</em>

<em>The radius is given as 3 inches</em>

Area = $3.14*3^{2} = 3.14*9 = 28.26$ cubic inches = 28.3 cubic inches

------------------------

<em>Perimeter is calculated with </em> $2\pi r$ <em>.</em>

<em>But this is 3/4 of a circle with an additional two 3-inch sides</em>

Perimeter = $\frac{3}{4}*2\pi r$ + 2(3) = 14.1 + 6 = 20.1 inches

Determine sum of the first 16 terms (S16) for an arithmetic series given the first tem is 9 (a = 9) and

Mekhanik [1.2K]

$\boxed{Sum=624}$

<h2>Explanation:</h2>

The nth term of an arithmetic series ( $a_{n}$ ) and the sum of an arithmetic series (Sum), for n terms, can be found as:

$a_{n}=a_{1}+d(n-1) \\ \\ Sum=\frac{n}{2}[2a_{1}+(n-1)d] \\ \\ \\ Where: \\ \\ a_{1}:First \ term \\ \\ d:Common \ difference \\ \\ n=Number \ of \ term$

So, in this exercise:

$a_{1}=a=9 \\ \\ d=4 \\ \\ n=16 \\ \\ \\ Sum=\frac{16}{2}[2(9)+(16-1)4] \\ \\ Sum=8[18+(15)4] \\ \\ Sum=8[18+60] \\ \\ Sum=8[78] \\ \\ \boxed{Sum=624}$
