coolman101: determine the area when given the circumference of 45cm
Hi Coolman,
Do you know the formula for the area and the circumference of a circle?
Since you know the circumference you can put that into the circumference formula and solve it for radius.
Then you can find the area with the area formula.
If you don't know the circle formulas you could google them and find them very easily I am sure
If you just typed in 'Formula for area of a cicle' I think the answer would come up almost immediately.
Happy calculations.
