A= 3
b= 4
=3.14(a^2 + ab)
substitute the given a & b values in expression
=3.14((3)^2 + (3*4))
multiply inside parentheses
=3.14(9 + 12)
add inside parentheses
=3.14(21)
multiply
=65.94
ANSWER: 65.94

Answer

To prove


= 0.54


= 0.5

= 1.00
Now we find out the mid point of the 0.5 and 1.00 .

(Mid point is the point lies middle of a line segment .)
Mid point = 0.75
Thus

This shows o.54 lies between 0.5 and 1.00
This means 0.54 lies right to 0.5 and left from 1.00 .
Therefore
