A would be 1 as b would be -4
Answer:
128 π
Step-by-step explanation:
A= π*r^2
Larger Circle = X
Smaller Circle = Y
In terms of π :
Area of x : 324 π
Area of y: 196 π
324 - 196 = 128π
Answer:
(2 x 100) + (6 x 10) + (804 x 10^-3)
Step-by-step explanation:
The figure located at the hundred must be multiplied by 100
The figure located at the tens must be multiplied by 10
The figure located at the ones must be multiplied by 1
The figure located at the tenth must be multiplied by 10^-1
The figure located at the hundredth must be multiplied by 10^-2
The figure located at the thousandths must be multiplied by 10^-3
All the previous expression must be added. Then, 2 hundreds, 6 tens, and 804 thousandths is the same as:
(2 x 100) + (6 x 10) + (804 x 10^-3) = 260.804
