Surface Area of cylinder = 8195.4 inches^2
Step-by-step explanation:
we are given:
Diameter of cylinder = 30 inches
Height of cylinder = 72 inches
We need to find:
Surface area of cylinder = ?
The formula used is:

We know radius = diameter/2
so, radius = 30/2 = 15 inches
putting values:

So, Surface Area of cylinder = 8195.4 inches^2

Step-by-step explanation:
Let its complementary angle be x.
So
81+x=90
so, x = 9.
so
complementary angle of 81° is 9°.
Answer:
(x+4)⋅(2x−7)
Step-by-step explanation:
Combine the like terms.
Answer:
x = 18
Step-by-step explanation:
Since that is a right angle, we know that the total degrees of the angle is 90 degrees.
1) Based off of that, you can form the equation: 3x + 2x = 90.
2) solve the equation for x. Combine like terms: 3x + 2x = 5x.
5x = 90
3) So now, divide both sides by 5. 90 / 5 = 18
x = 18
Therefore, the correct answer is x = 18.
