Find the area of each round your answer to the nearest tenth

Area of a circle- pi x r square

3.14 x 2 x 2

= 3.14 x 4

= 12.56

Round off- 13

12.7 ft^2

Step-by-step explanation:

to find the area, the equation is: r × r × π

we have the radius so we just plug the values into the equation, then into the calculator:

2 × 2 × π = 12.566 ft²

               ≈12.6 ft² (nearest tenth)

i believe that the nearest tenth is the tenths place in the decimal. hope this helped!

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14
