Alawn sprinkler spins in a circle. the sprinkler covers a radius of 12 feet. which choice is the closest to the area of lawn that the sprinkler can cover?

Step-by-step explanation:

The formula for the area of a circle is π r^2.

3.14 (12x12) = 452.16

Approximately 450sqft

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
