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.
Step-by-step explanation:
Answer:
-9 = 0.45m
Step-by-step explanation:

- ^ Subtract 0.45m from BOTH sides. so
... 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:
<-- 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
