Answer:

The answer to your question is below

Step-by-step explanation:

See the graph below

Process

1.- Find the distance from A to B, B to C, C to D, A to D

Formula

d = $\sqrt{(x2 - x1)^{2} + (y2 - y1)^{2}}$

d AB = $\sqrt{(1 + 3)^{2} + (6 - 5)^{2}} = \sqrt{17}$

dBC = $\sqrt{(-2 -6)^{2} + (3 - 1)^{2}} = \sqrt{68}$

dCD = $\sqrt{(-1 - 3)^{2} + (-3 +2)^{2}} = \sqrt{17}$

dAD = $\sqrt{(-1 + 3)^{2} + (-3 - 5)^{2}} = \sqrt{68}$

2.- Find the perimeter

Perimeter = 2 $\sqrt{17} + 2\sqrt{68}$ = $6\sqrt{17}$ u

3.- Find the area

Area = $\sqrt{17} x \sqrt{68}$

Area = $\sqrt{17x68} = \sqrt{1156} = 34 u^{2}$

Find the total surface area of this cylinder . Give your answer to 1 decimal place 7cm 15 cm

Leto [7]

Answer:

Step-by-step explanation:

r = 7 cm

h = 15cm

pi = 3.14

Top and bottom (These questions drive you crazy when you don't know if there is both a top and bottom).

Area = 2* pi *r^2 = 2 * 3.14 * 7^2

Area = 2 * 3.14 * 49

Area = 307.72 Don't round this.

Cylinder body

Cylinder body = Circumference * h = 2*pi * r * h

Cylinder body = 2* 3.14 * 7 * 15

Cylinder body = <u> 659.4</u>

<u />

Total = 967.12
