Answer: 2000/25 = 80 tiles

Step-by-step explanation:

Date: s=20

equation of surface area of a cube prism: surface area = 6s*2

the surface area to be covered with tiles is requires, the base is not included, so the equation reduces: surface area = 5s*2

subtitute values: surface area = 5(20)*2

= 5(400)

surface area = 2000

area of 2 tile is 5*2 = 25 square inches

2000/25 = 80 tiles

An earthquake was felt throughout a circular area of 1808.64 Square miles what was the radius of the circular area

lozanna [386]

Answer:

Step-by-step explanation:

The area of a circle is given by the formula:

$A=\pi r^2$

Where A is the area and r is the radius.

Since we already know the area, we can plug it in and solve for r. Thus:

$1808.64=\pi r^2\\$

Divide both sides by π. We can use 3.14 as an approximation. The πs on the right cancel out:

$1808.64\div(3.14)=r^2\\r^2=576$

Take the square root of each side:

$\sqrt{r^2}=\sqrt{576}$

The squares on the left cancel. The root of 576 is 24:

$r=24$

Therefore, the radius is 24.

Use Heron's Area Formula to find the area of the triangle. (Round your answer to two decimal places.)

aniked [119]

Answer:

1549.24

Step-by-step explanation:

Heron's Area formula:

A = $\sqrt{s(s - a)(s - b)(s - c)}$ , where s is semi-perimeter
s = 1/2(a + b + c)

We are given two sides and the included angle.

Use the law of cosines to find the missing side:

a² = b² + c² - 2bccos A
a² = 77² + 41² - 2*77*41*cos 79
a² = 6405
a = 80 (rounded)

Now find the value of s:

s = 1/2(80 + 77 + 41) = 99

Find the area:

A = $\sqrt{99(99 - 80)(99 - 77)(99 - 41)}$ = $\sqrt{2400156}$ = 1549.24
