Answer:
87.92 mm²
Step-by-step explanation:
Given:
- Radius of circular base: 2 millimeters
- Height of cylinder: 5 millimeters
<u>It should be noted:</u>
- Surface area of cylinder: 2πrh + 2πr² (R = Radius; H = Height)
When the measures are substituted, we get the following expression:
Multiply the constants and substitute π as 3.14.
- ⇒ 20π + 2π(4)
- ⇒ 20π + 8π
- ⇒ 20(3.14) + 8(3.14)
Finally, simplify the expression to determine the surface area.
- ⇒ 20(3.14) + 8(3.14)
- ⇒ 62.8 + 25.12
- ⇒ 87.92 mm²
Answer:
The slope is -1
Y-intercept is (0, -6)
Equation is y = -1x - 6 or y = -x - 6 either is right
Step-by-step explanation:
We already know that the slope is negative because the line is pointed this way \ pointed up to the left.
You have to do rise/run to find the slope.
The rise is 6 and the run is 6
6/6 = 1 since the line is negative the slope is -1x or -x
The y intercept is -6
Use the point (-2, -4)
Plug in
-4 = -(-2) + b
-4 = 2 + b (subtract 2 on both sides)
-6 = b
y = -x - 6
Hope this helps ya!!
Answer:
$6981
Step-by-step explanation:
Let's find the answer by using the following formula:
(this year cost)=(last year cost)+((last year cost)*(percent increase of cost)) so:
3750+3650=X+0.06X where X=last year cost, then:
7400=1.06X
6981.13=X
In conclusion, last year he spent $6981.
