To find the area of a circle, you can use the formula:
[ text{Area} = pi r^2 ]
Where ( r ) is the radius of the circle.
If you know the radius of the circle, just plug that value into the formula. For example, if the radius is 5 cm:
1. Square the radius: ( 5^2 = 25 )
2. Multiply by ( pi ): ( 25 times pi approx 25 times 3.14 = 78.5 )
So, the area would be approximately 78.5 cm².
Ensure you round your final answer to the nearest tenth as requested. Let me know if you need help with a specific value!
