ANSWER
EXPLANATION
Let R be the radius of the bigger circle and r, be the radius of the smaller circle.
Then their ratio is given as,
We can rewrite it as fractions to get,
We make R the subject to get,
The area of the bigger circle can be found using the formula,
This implies that,
But it was given in the question that, the area of the bigger circle is 27π.
We divide through by 9π to get,
This means that,
The area of the smaller circle is therefore
Using the given formula speed = distance over time:
Speed = 70 miles / 3 hours
Speed = 23.33 miles per hour
Convert miles per hour to meters per hour:
1 mile = 1609 meters:
23.33 miles x 1690 meters = 37,543.33 meters per hour.
Now convert meters per hour to meters per second:
1 hour = 3600 seconds:
37,543.33 / 3600 = 10.4 meters per second.
Since you know that when x = 2, y = 8, when you replace x with xb:
<span>8=(xb<span>)3</span></span>
x has been replaced by xb, so xb must equal 2
and then substituting in 0.5 for x, you can solve for b
<span><span>0.5b=2</span></span>
