16. A can in the shape of a cylinder has a diameter of 6 centimeters

sladkih [1.3K]

Answer:

surface area = 245.04 cm² (nearest tenth)

Step-by-step explanation:

Surface area of a closed cylinder = $2\pi r^2+2\pi rh$

Given:

diameter = 6 cm ⇒ radius = 3 cm
height = 10 cm

⇒ surface area = 2 × $\pi$ × 3² + 2 × $\pi$ × 3 × 10

= 78 $\pi$

= 245.04 cm² (nearest tenth)

Answer:

$a:b = -17:1$

Step-by-step explanation:

Given

$\frac{a-3b}{a+2b} = \frac{4}{3}$

Required

Find a:b

$\frac{a-3b}{a+2b} = \frac{4}{3}$

Cross Multiply

$3(a-3b) = 4(a+2b)$

Open brackets

$3a - 9b = 4a + 8b$

Collect Like Terms

$3a - 4a = 8b+9b$

$-a = 17b$

Divide through by -b

$\frac{-a}{-b} = \frac{17b}{-b}$

$\frac{a}{b} = \frac{17}{-1}$

$\frac{a}{b} = \frac{-17}{1}$

Represent as a ratio

$a:b = -17:1$

How do i find the slope-<br> 20 points answer!<br> [imagine below included!]

Dafna11 [192]

Answer:

3/3 = 1

Step-by-step explanation:

The slope formula is..

Pick two formulas. Let's do (-5, -2) and (-2, 1)

x1 y1 x2 y2

(-5, -2) (-2, 1)

$\frac{1-(-2)}{-2-(-5)}$ = $\frac{3}{3}$ = 1

It'll work the same thing for (-2, 1) and (1,4)...

3/3 or 1 is a pattern between the points.
