8 miles ? If I am correct
Answer:
1
Step-by-step explanation:
If you put in 12 for t, you might see what to do.
5 - 12 / 3
12 divided by 3 = 4
/ means divide
5 - 4 = 1
Area of a semicircle = 1/2 πr²
1/2 πr² = <span>76.97
Multiply both sides by 2:
</span>πr² = 153.94
Divide both sides by π:
<span>r</span>² = 49
Square root both sides:
r=√49
r = 7
Answer: r = 7
