Answer:
819.54 cm^2
Step-by-step explanation:
We are given
Slant height = l = 20cm
and
Diameter = d = 18 cm
We have to find radius first
r = d/2 = 18/2 = 9 cm
The formula for surface area is:

Answer:
{x | x ≤ -20}
Step-by-step explanation:
x + 17 ≤ -3

Answer:
x-int: (3, 0)
y-int: (0, -1.5)
Step-by-step explanation:
x-intercept is the x-value when y = 0
y-intercept is the y-value when x = 0
Step 1: Find x-intercept
0 = (x - 3)/2
0 = x - 3
x = 3
(3, 0)
Step 2: Find y-intercept
y = (0 - 3)/2
y = -3/2
(0, -1.5)
