33 letters in the russian alphabet

33

It goes 33 times.

Commit to memory

Area(of Circle)(A) = pi)3.141592....) Multplied to the radius squared (r^2)

Algebraically

A = pi*r^2

pi = 3.14 ( for elementary/school purposes)

r = 33

r^2 = 33^2

Substitute

A = 3.14 * 33^2

A = 3.24 X 33 X 33

On the calculator/

A = 3.14 X 1089

A = 3421.1944.... units^2

A ~ 3421.2 units^2

NB You do not give the units, but whatever, they are , they are squared. e.g. )cm^2)

5629.

-------------------------------

if (number ÷ 33 = 170 r 19) then:

number = 170 × 33 + 19 = 5629
