Use the distance formula to find the perimeter of the triangle below. Round you answer to the nearest hundredth.

Murrr4er [49]

jAlright, let's take this problem step-by-step:

What is the perimeter:

⇒ all the side-lengths added up

⇒ need to find side-length using distance formula

$Distance_._. Formula=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

- (x₁,y₁): first point

- (x₂,y₂): second point

Let's solve:

Find length of AC

⇒ first point: (5,7)

⇒ second point: (3,3)

$Distance =\sqrt{(3-5)^2+(3-7)^2} =\sqrt{4+16} =\sqrt{20} =4.472$

Find length of AB

⇒ first point: (5,7)

⇒ second point:(8,6)

$Distance=\sqrt{(8-5)^2+(6-7)^2} =\sqrt{9+1} =\sqrt{10}=3.162$

Find length of BC

⇒ first point: (8,6)

⇒ second point: (3,3)

$Distance = \sqrt{(3-8)^2+(3-6)^2} =\sqrt{25+9} =\sqrt{34}=5.831$

Now let's solve for the perimeter:

$Perimeter = 4.472+ 3.126+ 5.831=13.429$

Answer: 13.43 (rounded to the nearest hundredth)

Hope that helps!

A solid circular cylinder has a base radius 5 cm and a height 12.5 cm. Find the approximate increase in the surface area of the

Olin [163]

Answer:

19.72 cm²

Step-by-step explanation:

A solid circular cylinder has a base radius 5 cm and a height 12.5 cm.

The volume of cylinder is given by :

$V=\pi r^2 h\\\\=3.14\times (5)^2\times 12.5\\\\=981.25\ cm^2$

When r = 5.05, new volum becomes,

$V=\pi r^2 h\\\\=3.14\times (5.05)^2\times 12.5\\\\=1000.97\ cm^2$

Increase in area = 1000.97 - 981.25 = 19.72 cm²

So, the increase in surface area of the cylinder is equal to 19.72 cm².
