Mathematics
1 answer:
konstantin123 [22]3 years ago
4 0

Answer:

(n + 1)²

Step-by-step explanation:

note that 4, 9, 16, 25, 36 are square numbers

To generate the terms add 1 to the position n and square, that is

first term : n = 1 → n = 1 + 1 → 2² = 4

second term : n = 2 → n = 2 + 1 → 3² = 9

third term : n = 3 → n = 3 + 1 → 4² = 16

Hence n th term is (n + 1)²

What would the area of an actual pool be in the scale from the drawing is 3:1000
elena55 [62]

Answer:

If this is the complete question them the answer is 1250 m²

Step-by-step explanation:

the pool in the drawing is 15x7.5 and the scale is 3/1000 so if the size in the drawing  is 3 then the actual is 1000.

x=15*1000/3=5000cm which would be 50m

x=7.5*1000/3=2500cm which is 25m

the actual area of the pool is 50*25=1250 m²

Help please been stuck on this for a week.
Anettt [7]
They give the formula as:
Surface Area =<span> (2 • <span>π <span>• r²) + (2 • <span>π • r • height)</span></span></span></span>
However the 2*PI*r^2 part of the formula is used to calculate the 2 "ends" of a cylinder.  Since the problem states that you are NOT to count any of surface area of the "ends" then you only need the <span>(2 • <span>π • r • height) part of the formula.
So, r = 3 inches and height = 8 * 3 inches, the side area equals
2 * PI * r * height
2 * 3.14159 * 3 * 24 =
</span></span>
<span> <span> <span> 452.39 cubic inches which is the lateral area.</span></span></span>
