The distants around the edge of the pool is 38 feet. What is the area the pool with cover

kvv77 [185]

Answer:

$114.93 ft$

Step-by-step explanation:

$\pi = 3.14$

Given formula to find the area:

$\pi * r^2$

Find radius first:

$Circumference = \pi * 2 * r$

The circumference in this situation would be 38 feet.

$38ft = \pi * 2 * r$

$38 ft = 3.14 * 2 * r$

$3.14 * 2 = 6.28$

$38ft = 6.28 * r$

Since we need to find radius, do division to 38 by 6.28.

$38ft / 6.28 = 6.05$

Our radius is 6.05

Now back to the original formula which is:

$\pi * r^2$

Substitute:

$A = 3.14 * 6.05^2$

$6.05^2 = 36.6$

$A = 3.14 * 36.6$

$==> 114.93ft$

Find the common difference of the arithmetic sequence 1, -1, -3,...

ivanzaharov [21]

Answer:

Step-by-step explanation:

Notice that each new term in the arithmetic sequence 1, -1, -3, ... is 2 less than the previous term. Thus, the common difference is -2.

The formula for this sequence is a(n) = 1 - 2(n - 1), or a(n) = 3 - 2n

What is the solution to the equation?

pashok25 [27]

Answer:

x= 27

Step-by-step explanation:

Move constant to the right-hand side and change its sign.

$\sqrt{2x+10}$ = 2+6

Add the numbers.

$\sqrt{2x+10}$ = 8

Square both sides of the equation.

2x+10= 64

Move the constant to the right-hand side and change its sign.

2x= 64-10

Subtract the numbers.

2x= 54

Divide both sides of the equation by 2.

x= 27
