Given:
Radius of a cylinder = 5 units.
Surface area of the cylinder = 
To find:
The height of the right cylinder.
Solution:
Surface area of a cylinder is:

Where, r is radius and h is the height of the cylinder.
Putting
in the above formula, we get



Subtract
from both sides.


Divide both sides by
.


Therefore, the height of the cylinder is 11 units.
Answer:
x = 1
y = 3
Step-by-step explanation:
2x + 1 = y ------- eqn (1)
2y = 6--------eqn (2)
from eqn(2)
2y = 6
y = 3
when you divide 6 by 2y
substitute y = 3 into eqn (1)
2x + 1 = y
2x + 1 = 3
2x = 3-1
2x = 2
therefore
x = 1
Answer:

Step-by-step explanation:
If 5! is equal to 5 × 4 × 3 × 2 × 1 and 6! is equal to 6 × 5 × 4 × 3 × 2 × 1, then 4! is equal to 4 × 3 × 2 × 1. Thus, 4! = 4 × 3 × 2 × 1, which can simplify to 24. 4! = 24.
is basically 4 × 4 × 4 × 4, which can simplify to 256.
So,
=
.
can simplify to
. Therefore,
=
.
