Umm, yeah. Your profile says you're a 7th grader. So HOW exactly is this *your* childs homework?????
Maybe you should spend more time paying attention in class and less time daydreaming and you could figure out your own homework answers.
Sorry to be rude about it but school's only going to get harder once you're in 8th, 9th, etc grades. You might as well really learn this stuff now and not rely on strangers to do it for you.

Let me get my math book out.
Well the diameter is a line that passes through the center of a circle and goes all the way through. And the radius is the line that passes through the circle, but stops in the middle of the circle. Its hard to say it, but say you have a circle and put a dot in the center of it. To make the diameter, draw a line from the outside of the circle all the way past the dot and to the other side. You should draw this out for your daughter to better understand. The radious would be if you have the circle with the dot in the middle, and you draw the line coming from the outside of the circle, but stop at the dot. So therefore 2 radiuss add to make the diameter.
1) Just take the diameter and divide by 2...which is 22inches.
2) Take the radius and times it by 2...which is 3.8 inches.
3) The circumfrence is the distance around the circle and so you would times the number by pi by the diameter. and radius would be 2piR...the answer is 6.28
4) it would be 28.26
5) 20.096
6) 58.718
7) 37.68
8) 32.028
9) 1.046 .5233
11) 3.248 1.624
12) .157 .0785
Hope it helped, sorry if some of them are wrong, im doing this right before bed and im really tired. Good night.

You seriously don't know this? Lol...wow.
Here's a start for you: The diameter is the distance across a circle; the radius is the distance from the centre of a circle to the edge, and therefore the radius is half of the diameter. If, like in question #1, the diameter is 44, than the radius is 22.
What is this, like grade 4 work?!

The diameter is how far it is across a circle. The radius is how far it is from the center of the circle to the outside of the circle (half the diameter). The circumference it the distance around the outside of the circle. Circumference (C) equals the diameter (d) times pie (about 3.14). So C= pie x d.

So what are your questions? Whenever I had homework it was based upon what I learned in school that day. Why can't your daughter do her own homework? What is she doing in class if not learning? Call the teacher & ask her what she taught & if homework is based on that.

Surely it would be quicker to calculate the answers to these questions than to type them all in? It you're not sure how to complete them, do a Google search for the processes.

radius=diameter/2
Circumference= pi x diameter
