1. T
2. Use the circumference formula to find the radius. Then use the area formula to find the area.
3. Solve it same way as 2.
4. Use the area formula to find the radius. Then use the circumference formula to find the circumference.
If you have questions, just ask.
cant remember the area formula for a circle
can you work out number 2 for me?
