Step-by-step explanation:
Hello, we cannot see the ellipse equations.
The eccentric of an ellipse is given by:
Assuming the equations are:
Then a²=25 and b²=16
The eccentricity is:
If the ellipse has equation,
then the this time, we have a=5 and b=3.
This means that:
Answer:
Step-by-step explanation:
2 more than 3 time mean 3n+2
"is atleast 8" means it can be 8 or more so c. is right answer
If he does three hours, its 9 strips, for four, its 12, six is 18, seven is 21, and nine is 27
Answer:
<h2>
CYLINDER</h2>
Surface Area = 471.2 cm^2
<h2>
TRIANGULAR PRISM</h2>
Surface Area = 60.75 m^2
Step-by-step explanation:
<h2>
CYLINDER</h2>
The surface area formula for a cylinder is π x diameter x (diameter / 2 + height), where (diameter / 2) is the radius of the base (d = 2 x r), so another way to write it is π x radius x 2 x (radius + height). ( π =3.14 )
FORMULA:
π x 5 x 2 x 15
WORK:
π x 5 = 15.7
15.7 x 2 = 31.4
31.4 x 15 = 471
<h2>
TRIANGULAR PRISM</h2>
The surface area formula for a triangular prism is 2 * (height x base / 2) + length x width1 + length x width2 + length x base.
FORMULA:
2 x (2.5 x 1.5/2) + (6 x 4) + (6 x 4) + (6 x 1.5)
WORK:
(2.5 x 1.5) = 3.75/2 = 1.875
1.875 x 2 = 3.75
(6 x 4) = 24
(6 x 4) = 24
(6 x 1.5) = 9
3.75 + 24 + 24 + 9 = 60.75
