<h3>What is a cylinder?</h3>
A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The circular bases' centers overlap each other to form a right cylinder.
The curved surface area of a single-cylinder with a diameter of 2.5 feet and a height of 22 feet will be,
Curved surface area = πDh = π × 2.5 × 22 = 172.7875 ft²
The total area of 20 pillar = 20 × 172.7875 ft² = 3,455.75191 ft²
Since a gallon of paint can cover only 350 ft², therefore, the amount of paint that will be needed to paint 3,455.75191 ft² can be written as,
Hence, the amount of paint needed to paint 20 pillars is 9.874 gallons.

Answer:
i think Banu is 40 and Binu is 20
Step-by-step explanation:
if Banu was 35 and Binu was 15, 5 years go by Banu is 40 so still 20 years older and Binu is 20, Binu is half the age of Banu.
Answer:
x = -2 or -18.
Step-by-step explanation:
(x+7)^2 + 6x = 13
x^2 + 14x + 49 + 6x - 13 = 0
x^2 + 20x + 36 = 0
(x + 2)(x + 18) = 0
x = -2, -18.
Answer:
Explanations:
Note that for a sequence to be arithmetic, there must be a common difference, d.
Considering each of the sequences provided:
For -1, 3, -9, 27, -81.........
3 - (-1) = 4
-9 - 3 = -12
27 - (-9) = 36
Since the differences between consecutive terms are not common, this is not an arithmetic sequence.
For 1, -2, -5, -8, -11....
-2-1 = -3
-5 -(-2) = -3
-8 - (-5) = -3
-11 - (-8) = -3
Since there is a common difference, d = -3, the sequence is an arithmetic sequence
For 26, 39, 52, 65, 78.....
39 - 26 = 13
52 - 39 = 13
65 - 52 = 13
78 - 65 = 13
Since there is a common difference of
