This is the formula for the surface area of a cylinder including the ends, like the total surface area of a can of peas.
S = 2·π·r² + 2·π·r · H
Divide each side by 2·π·r :
S/2·π·r = r + H
Subtract r from each side :
H = (S/2·π·r) - r
or
H = (S - 2·π·r²) / (2·π·r)
the answer is 7/6. hope it is right
Answer:
It contains fewer hydrogen ions.
Step-by-step explanation:
For the graph in the figure below, we can notice that when (H) increases, -log(H) decreases.
So if pH > 7.0, it must indicate that there is a small number of hydrogen ions per liter. Knowing that pH of water is 7, that indicates that are fewer hydrogen ions.
Total = Principal * (1 + rate)^years
Total = 1,300 * (1.0475) ^ 5
Total = 1,300 *

Answer:
10.92
Step-by-step explanation:
1. Find all side lengths of this tetrahedron.
A to B is 2 units
A to C is 2 units
A to D is 2 units
B to C is square root of 8
B to D is square root of 8
C to D is square root of 8
See 3D distance formula attached below to get the answers above.
2. Find the area of the triangles
Triangle ACD can be calculated using Heron’s formula, which is also attached below.
Area of Triangle ACD is 2 units squared.
Area of Triangle ABD is congruent to the previous one so it is also 2 units squared.
Area of Triangle CBD is roughly 3.46 units squared.
Area of Triangle ABC is congruent to Triangle CBD so it is also 3.46 units squared.
Adding them altogether is 2 + 2 + 3.46 + 3.46 = 10.92
