Answer: Area of a right circular Cylinder--- curved surface area -2πrh Total surface area -2πr(r+h),where 'r' is the radius of the circular surface and 'h' is the height of the cylinder.
The area shaded in green is 864 cm²
<h3>Similar figures</h3>
Similar figures, corresponding angles are congruent and the sides are ratio of each other. Therefore,
AB / PQ = CD / RS
30 / 10 = 24 / RS
30RS = 240
RS = 240 / 30
RS = 8 cm
let find the height of trapezium PQRS.
AB / PQ = 36 / h
30 / 10 = 36 / h
30h = 360
h = 360 / 30
h = 12 cm
Therefore,
area of the green portion = area of ABCD - area of PQRS
<h3>Area of a trapezium</h3>
Therefore,
area of ABCD = 1 / 2(24 + 30)36 = 1 / 2 (54)36 = 1944 / 2 = 972 cm²
area of PQRS = 1 / 2(10 + 8)12 = 1 / 2(18)12 = 216 / 2 = 108 cm²
Area of the green portion = 972 - 108 = 864 cm²

The answer is 2.
it’s adding 2 everytime!
Answer:
x = 9
Step-by-step explanation:
Given
5x - 31 = 23 - x ( add x to both sides )
6x - 31 = 23 ( add 31 to both sides )
6x = 54 ( divide both sides by 6 )
x = 9
<u><em>Answer:</em></u>
Craig earns $1,200 each month
<u><em>Explanation:</em></u>
We are given that Craig pays a total of $720 each year for his telephone service
We also know that a year has 12 months
<u>This means that:</u>
Craig pays 
dollars each month for his telephone services
We are given that the monthly phone bill is 
of his monthly earnings
Assume that his monthly payment is x
<u>We have:</u>
dollars
Hope this helps :)
