π = 3.142
π x r x r
= π x 5 x 5 (radius)
= 78.5m3
You could also write π x r x r
That is how you find the area of a circle. We use pi and this formula to make it easier for ourselves instead of counting each individual square in the circle.

Area of a Circle
We have been learning about finding the area of a circle. The formula for this is
π = 3.142
π x r x r
= π x 5 x 5 (radius)
= 78.5m3
You could also write π x r x r

To support my learning I ask you to comment as follows:
1. Something positive - Begin with a greeting. Talk about something you like about what I have shared.
2. Thoughtful - A comment that will mean something to me to let me know you read/watched or listened to what I had to say. - use any language.
3. Something helpful - Give me some ideas for next time or ask me a question.
Encourage me to make another post
