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:

$A = 3.14 * 6.05^2$

$6.05^2 = 36.6$

$A = 3.14 * 36.6$

$==> 114.93ft$

X² + 4x + 3 = 0 Can someone please help me solve this quadratic equation

gavmur [86]

Answer:

Step-by-step explanation:

x= -1 and -3

What when multiplied is +3 but when added is 4? 3 and 1. You then get (x+3)(x+1) is the first part of the answer. If you want to find x, set x+3 to 0. x+3=0. Then subtract 3 from both sides to get x by itself. x= -3. Do the same with the x+1.
