To find the surface area, use the formula for surface area of a cylinder:
S.A. = 2πrh + 2πr², where r is the radius and h is the height.
The radius and height are given as follows.
r = 5
h = 16
Plug these values into the formula and solve to find the S.A.
S.A. = 2πrh + 2πr²
S.A. = 2π(5)(16) + 2π(5)²
S.A. = 2π80 + 2π25
S.A. = 160π + 50π
S.A. = 210π
Since we are leaving our answer in terms of pi, we don't need to do anything more.
Answer:
S.A. = 210π cm²
x - 2 ≥ 0
Step-by-step explanation:
The expression under the square root cannot be negative, thus
x - 2 ≥ 0 , that is
x ≥ 2
x + 1/2 = 3/4
set denominators equal:
x + 2/4 = 3/4
-2/4 for both sides:
x = 1/4
