Let $S = 2010 + 2011 + \cdots + 4018$. Compute the residue of $S$, modulo 2009.

Yakvenalex [24]

Notice that

2010 ≡ 1 mod 2009

2011 ≡ 2 mod 2009

2012 ≡ 3 mod 2009

...

4017 ≡ 2008 mod 2009

4018 ≡ 0 mod 2009

So really, S is just the sum of the first 2008 positive integers:

$S=\displaystyle\sum_{n=1}^{2008}n=\frac{2008\cdot2009}2$

where we invoke the formula

$\displaystyle\sum_{i=1}^ni=\frac{n(n+1)}2$

and so S ≡ 0 mod 2009.

$\mathcal \pink{GIVEN:}$

Radius = 3 m
Height = 7 m

$\mathcal \purple{TO \: FIND:}$

Volume = ?

$\mathcal \blue{CALCULATION:}$

$\qquad{ \sf \: volume = \pi{r}^{2}h }$

Where,

r is radius
h is height

$\qquad{ \tt\nrightarrow \: \frac{22}{7} \times {3}^{2} \times 7}$

$\qquad{ \tt\nrightarrow \: \frac{22}{ \cancel7} \times {3}^{2} \times \cancel7}$

$\qquad{ \tt\nrightarrow \: 22 \times {3}^{2} }$

$\qquad{ \tt\nrightarrow \: 22 \times 9 }$

$\qquad{ \boxed{ \tt\Rrightarrow \: 198\: {m}^{3} }}$

➪ Henceforth, The volume of the cylinder is 198 m³...
