Answer:
Step-by-step explanation:
Area is pi times r squared. I don't know how to write that on the keyboard. Take your pi(3.142) times the radius(6.2)squared. Pemdas tell us to do exponents first, so 6.2 squared is 38.44. To square a number, just multiply it times itself. So now, we have pi(3.142) times the squared radius(38.44). So, 3.142X38.44=
120.778 Second place is seven followed by eight. Round up. 120.78
Where’s the picture, sugar cube?
