Answer:

7. Approximately 402.7 inches or 2pi times 64

8. 31.83 To solve this you know 2pi r is an equation for the radius. 2πr=200 and r=200/2π=100/π= 31.83.

9. The one with pi in the equation because 3.14 is only a piece of pi but the symbol represents the whole number which goes on forever.

Answer:

-9 = 0.45m

Step-by-step explanation:

$0.45m - 9 = 0.9m$

^ Subtract 0.45m from BOTH sides. so $0.9m - 0.45m$ ... etc
Why? So that we can make the equation less complicated. Our goal is to isolate the variable m to be on one side of the "=" sign by itself
That will equal to:

$-9 = 0.45m$ <-- ANSWER

(1/4)x = 2

x = 8 x 3 = 24 feet long

(1/4)x = 1

x = 4 x 3 = 12 feet wide

24ft x 12ft = 288ft^2
