Answer:
1507m²
Step-by-step explanation:
Given parameters:
Radius of cylinder = 12m
Height of cylinder = 8m
π = 3.14
Unknown:
Surface Area of cylinder = ?
Solution:
The surface area of any body is the sum of all the area that covers a body.
For a cylinder, the surface area is given as;
SA = 2πr² + 2πrh
Where SA = Surface Area
r = radius of cylinder
h = height of cylinder
Now input the parameters in the given equation and solve;
SA = (2 x 3.14 x 12²) + (2 x 3.14 x 12 x 8)
SA = 904.32 + 603.264
SA = 1507.584m² = 1507m²

Step-by-step explanation:
let's take a peek at the graph.
the graph of the equation touches the x-axis at 1, 2 and 3, at 1 it crosses it, at 2 it crosses it, at 3 is doesn't cross it, it simply bounces off of it.
on the roots/solutions the graph crosses the x-axis, they have ODD multiplicity, on the solutions it bounces off of it, they have EVEN multiplicity, so then.
x = 1 => x - 1 = 0 <------ one factor
x = 2 => x - 2 = 0 <------ another factor
x = 3 => x - 3 = 0 <------ another factor, BUT with even multiplicity
(x-1)¹(x-2)¹(x-3)² = f(x)
(x-1)(x-2)(x-3)² = f(x).
Answer:
<u>45,000 people</u>
Step-by-step explanation:
<u>Simplifying the expected ratio</u>
- 6/8 people use toothpaste
- ⇒ <u>3/4</u>
<u></u>
<u>Multiply the ratio with 60,000</u>
- 60,000 x 3/4
- 15,000 x 3
- <u>45,000 people</u> can be expected to use Clean-White toothpaste
It would be .2 not 2 because the smaller number is first
2 divided by 10 is .2
