Answer:
Nina's rate in miles per hour is 2.7 miles/hour
Nina bikes faster
Step-by-step explanation:
we know that
1 hour=3,600 seconds
1 mile=5,280 feet
<em>Convert feet to miles</em>
63,360 feet=63,360/5,280=12 miles
Convert seconds to hours
3,400 sec=3,400/3,600=0.94 hours
Find Nina's rate in miles per hour
12/0.94=12.7 miles/hour
Sophia's rate in miles per hour is 10 miles/hour
Compare the rates
12.7 miles/hour > 10 miles/hour
therefore
Nina bikes faster
<em>a. 2√21 units</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<u><em>Area formula</em></u>
<em>A = π·r²</em>
<em>84π = πr²</em>
<em>r² = 84π/π</em>
<em>r² = 84</em>
<em>r² = 2²×3×7</em>
<em>r = √2²×3×7</em>
<em>r = 2√3×7</em>
<em>r = 2√21</em>
<em>Good luck !</em>
