90 is the LCM of 30 and 45
Given:
Radius of the cylinder = 5 in
Height of the cylinder = 30 in.
To find:
The surface area of the cylinder.
Solution:
The surface area of the cylinder is:

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




Therefore, the surface area of the cylinder is 1099 square inches.
Answer:
since highest degree is 2 the degree of a polynomial is also 2.
since the highest exponent is 2 the leading coefficient is 1.
