Answer:
Area of the shaded part is 3.14 square unit.
Step-by-step explanation:
Area of the shaded part = Area of large semicircle - (Area of two small semi circles)
Area of large semicircle with center O = 
= 
= 2π
Area of semicircle with center O' = 
= 
Area of semicircle with center O" = 
Now substitute these values in the formula,
Area of shaded part =
=
= 3.14 square unit
Area of the shaded part is 3.14 square unit.
Answer:
Step-by-step explanation:
If the smallest number is 'x', then the other number = x +1
x*(x+1)= 420

x*x + x*1 = 420
x² + x - 420 =0 ------> this is the required quadratic equation.

Step-by-step explanation:
11+y is an expression that contains a variable ‘y’
then its value depends on ’y’
examples :
if y = 0 → 11+y = 11+0 = 11
if y = 1 → 11+y = 11+1 = 12
if y = 2 → 11+y = 11+2 = 13
and so on.
