Im stuck can someone explain this please

Step-by-step explanation:

For this problem, we should mainly focus on the numbers.

The free throw line on a college basketball court is 12 feet wide.

The free throw line on a basketball court in a park is 11.3 feet wide.

So far we have the numbers 12, and 11.3.

Our question is How much longer is the half-circle above the free-line on the college basketball court than your neighborhood court.

What this means is that we are finding the difference between the two basketball free throw lines. However, it mentions it being a half-circle. The perimeter of a normal circle is π × d where d is the diameter so half of that is 1/2 (π × d). The numbers we got will be plugged in for d.

1/2 (π × 12) = ?

1/2 (π × 11.3) = ?

Plug these into a calculator. Once you do that, subtract them together and you'll find your answer!

I hope that helped at least a little bit, and gave you just a bit of guidance! I haven't actually learned this kind of stuff yet, but I took my best guess! I hope you have an awesome day! :D

P.S if anything I did is wrong or your still not sure, just guess the answer is 0.7π! I apologize if my answer is wrong so take it with a grain of salt!

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
