Answer:
Surface area of cylinder= 211.5π
Step-by-step explanation:
Given,
Height of cylinder = 19cm
Diameter of cylinder = 9cm
i.e Radius of cylinder = diameter/2 = 9/2 = 4.5cm
Surface area of cylinder = 2πrh + 2πr²
Plug corresponding values of r and h in surface are formula.
Surface area of cylinder = 2πrh + 2πr² = 2π*4.5*19 + 2π*4.5²
Surface area of cylinder = 171π+40.5π = 211.5π
Hence we get surface area of cylinder= 211.5π
Answer:
D
Step-by-step explanation:
Answer:
3.16 units
Step-by-step explanation:
The distance between the points P1 (6, 8) and P2 (7, 5)) can be solved by using the distance formula given as
.
Let,


Plug these values into the distance formula.
Thus:




d = 3.16 (nearest tenth)
Distance between the two points in the graph is approximately 3.16 units
Answer:
wish i could help but im in school so i cant see the picture<3:(
Step-by-step explanation:
<em>x = 20/7</em>
<em>x = 2 6/7</em>
- Step-by-step explanation:
<em>Hi there !</em>
6x - 9 - 2(1 - x) = x + 9
<em>6x - 9 - 2 + 2x = x + 9</em>
<em>6x + 2x - x = 9 + 9 + 2</em>
<em>8x - x = 20</em>
<em>7x = 20</em>
<em>x = 20/7</em>
<em>x = 2 6/7</em>

<em>Good luck !</em>
