I used the Old Change New method and I crossed multiplied.
The answer is about $498 (I rounded $497.895875)
Check: $498>459.95 by 8.25%
Look at the answers and compare the side lengths in the diagram to those. You don't need any math to see the logical answer here, the answer is most likely 14.3 units.
Answer:
r = 7 ft
Step-by-step explanation:
The circumference (C) of a circle is calculated as
C = 2πr ( r is the radius )
Here C = 43.96 , then
2πr = 43.96 ( divide both sides by 2 × 3.14 ← for π )
r =
=
= 7 ft
I think question 2 is 3 millimeters
Because diameter = 2r (R = radius)
